   PRECIS Framework: Preparation and Comparison of Internationalized
                    Strings in Application Protocols
                     draft-ietf-precis-framework-03

Abstract

   Application protocols using Unicode code points in protocol strings
   need to prepare such strings in order to perform comparison
   operations (e.g., for purposes of authentication or authorization).
   This document defines a framework enabling application protocols to
   handle various classes of strings in a way that depends on the
   properties of Unicode code points and that is agile with respect to
   versions of Unicode; as a result, this framework provides a more
   sustainable approach to the handling of internationalized strings
   than the previous framework, known as Stringprep (RFC 3454).  A
   specification that reuses this framework can either directly use the
   base string classes or subclass the base string classes as needed.
   This framework takes an approach similar to the revised
   internationalized domain names in applications (IDNA) technology (RFC
   5890, RFC 5891, RFC 5892, RFC 5893, RFC 5894) and thus adheres to the
   high-level design goals described in RFC 4690, albeit for application
   technologies other than the Domain Name System (DNS).  This document
   obsoletes RFC 3454.

Internet-Draft              PRECIS Framework                    May 2012


1.  Introduction

   As described in [I-D.ietf-precis-problem-statement], many IETF
   protocols use the Stringprep framework [RFC3454] as the basis for
   preparing and comparing protocol strings that contain Unicode code
   points [UNICODE].  The Stringprep framework was designed during work
   on the original technology for internationalized domain names (IDNs),
   commonly called "IDNA2003" [RFC3490], and Nameprep [RFC3491] was a
   Stringprep profile for the IDN case.  At the time, Stringprep was
   designed as a general framework so that other application protocols
   could use define their own Stringprep profiles for the preparation
   and comparison of strings and identifiers in these protocols, and a
   number of application protocols did define such profiles.

   Since that time, several significant issues arose with the use of
   Stringprep in the IDN case, as documented in [RFC4690] (most
   significantly, Stringprep was tied to Unicode version 3.2).
   Therefore, the new IDNA specifications, called "IDNA2008" ([RFC5890],
   [RFC5891], [RFC5892], [RFC5893], [RFC5894]), no longer use Stringprep
   and Nameprep.  This migration away from Stringprep for
   internationalized domain names has prompted other "customers" of
   Stringprep to consider new approaches to the preparation and
   comparison of internationalized strings (a.k.a.  "PRECIS"), as
   described in [I-D.ietf-precis-problem-statement].

   This document defines a technical framework for a post-Stringprep
   approach to the preparation and comparison of internationalized
   strings in application protocols.  The framework is based on several
   principles:

   1.  Define a small set of base string classes appropriate for common
       application protocol constructs such as usernames and free-form
       strings.

   2.  Define each base string class in terms of Unicode code points and
       their properties so that an algorithm can be used to determine
       whether each code point or character category is valid,
       disallowed, or unassigned.

   3.  Enable application protocols to subclass the base string classes,
       mainly to disallow particular code points that are currently
       disallowed in the relevant application protocol (e.g., characters
       with special or reserved meaning, such as "@" and "/" when used
       as separators within identifiers).

   4.  Leave various mapping operations (e.g., case preservation or
       lowercasing, Unicode normalization, right-to-left characters) as
       the responsibility of application protocols, as was done for

       IDNA2008 through an IDNA-specific mapping document [RFC5895].

   It is expected that this framework will yield the following benefits:

   o  Application protocols will be more version-agile with regard to
      the Unicode database.
   o  Implementers will be able to share code point tables and software
      code across application protocols, most likely by means of
      software libraries.
   o  End users will be able to acquire more accurate expectations about
      the code points that are acceptable in various contexts.  Given
      this more uniform set of string classes, it is also expected that
      copy/paste operations between software implementing different
      application protocols will be more predictable and coherent.

   Although this framework is similar to IDNA2008 and borrows some of
   the character categories defined in [RFC5892], it defines additional
   string classes and character categories to meet the needs of common
   application protocols.


2.  Terminology

   Many important terms used in this document are defined in
   [I-D.ietf-precis-problem-statement], [RFC6365], [RFC5890], and
   [UNICODE].

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in
   [RFC2119].


3.  String Classes

   IDNA2008 essentially defines a base string class of internationalized
   domain name, although it does not use the term "string class".  (This
   document does not define a string class for domain names, and
   application protocols are strongly encouraged to use IDNA2008 as the
   appropriate method to prepare domain names and hostnames.)  Because
   the IDN string class is designed to meet the particular requirements
   of the Domain Name System (DNS), additional string classes are needed
   for non-DNS applications.

   Starting in 2010, various "customers" of Stringprep began to discuss
   the need to define a post-Stringprep approach to the preparation and
   comparison of internationalized strings.  As a result of analyzing
   existing Stringprep profiles, this community of customers concluded

Internet-Draft              PRECIS Framework                    May 2012


   that most existing uses could be addressed by two base string
   classes:

   NameClass:  a sequence of letters, numbers, and symbols that is used
      to identify or address a network entity such as a user account, a
      venue (e.g., a chatroom), an information source (e.g., a data
      feed), or a collection of data (e.g., a file); the intent is that
      this class will be very safe for use in a wide variety of
      application protocols, with the result that safety has been
      prioritized over inclusiveness for this class.

   FreeClass:  a sequence of letters, numbers, symbols, spaces, and
      other code points that is used for free-form strings, including
      passwords and passphrases as well as display elements such as
      human-friendly nicknames in chatrooms; the intent is that this
      class will allow nearly any Unicode character, with the result
      that inclusiveness has been prioritized over safety for this class
      (e.g., protocol designers, application developers, service
      providers, and end users might not understand or be able to enter
      all of the characters that can be included in the FreeClass).

   Although members of the community discussed the possibility of
   defining other bases string classes (e.g., a class falling somewhere
   between the NameClass and the FreeClass), they concluded that the
   NameClass would be a safe choice meeting the needs of many or even
   most application protocols, and that protocols needing a wider range
   of Unicode characters could subclass the FreeClass.  Naturally,
   future documents can define additional string classes if needed.

   The following subsections discuss the NameClass and FreeClass in more
   detail, with reference to the dimensions described in Section 3 of
   [I-D.ietf-precis-problem-statement].  In particular, each string
   class is defined by the following behavioral rules:

   Valid:  defines which code points and character categories are
      treated as valid input to preparation of the string.

   Disallowed:  defines which code points and character categories are
      treated as disallowed during preparation of the string.

   Unassigned:  defines application behavior in the presence of code
      points that are unassigned, i.e. unknown for the version of
      Unicode the application is built upon.

Internet-Draft              PRECIS Framework                    May 2012


   Directionality:  defines application behavior in the presence of code
      points that have directionality, in particular right-to-left code
      points as defined in the Unicode database (see [UAX9]).

   Casemapping:  defines if case mapping is used for this class (instead
      of case preservation), and how the mapping is done.

   Normalization:  defines which Unicode normalization form (D, KD, C,
      or KC) is to be applied (see [UAX15]).

   This document defines the valid, disallowed, and unassigned rules.
   Application protocols that use the PRECIS string classes MUST define
   the directionality, casemapping, and normalization rules, as further
   described under Section 9.2.

3.1.  NameClass

   Most application technologies need a special class of strings that
   can be used to refer to, include, or communicate things like
   usernames, file names, data feed names, and chatroom names.  We group
   such things into a bucket called "NameClass" having the following
   features.

3.1.1.  Valid

   o  Traditional letters and numbers, i.e., the LetterDigits ("A")
      category first defined in [RFC5892] and listed here under
      Section 6.1.
   o  Code points in the range U+0021 through U+007E, i.e., the ASCII7
      ("K") rule defined under Section 6.11.  These code points are
      valid even if they would otherwise be disallowed according to the
      property-based rules specified in the next section.

3.1.2.  Disallowed

   o  Control characters, i.e., the Controls ("L") category defined
      under Section 6.12.
   o  Ignorable characters, i.e., the PrecisIgnorableProperties ("M")
      category defined under Section 6.13.
   o  Space characters, i.e., the Spaces ("N") category defined under
      Section 6.14.
   o  Symbol characters, i.e., the Symbols ("O") category defined under
      Section 6.15.
   o  Punctuation characters, i.e., the Punctuation ("P") category
      defined under Section 6.16.
   o  Any character that has a compatibility equivalent, i.e., the
      HasCompat ("Q") category defined under Section 6.17.  These code
      points are disallowed even if they would otherwise be valid

Internet-Draft              PRECIS Framework                    May 2012


      according to the property-based rules specified in the previous
      section.
   o  Letters and digits other than the "traditional" letters and digits
      allowed in IDNs, i.e., the OtherLetterDigits ("R") category
      defined under Section 6.18.

3.1.3.  Unassigned

   Any code points that are not yet assigned in the Unicode character
   set SHALL be considered Unassigned for purposes of the NameClass.

3.1.4.  Directionality

   The directionality rule MUST be specified by each application
   protocol that uses or subclasses the NameClass.

3.1.5.  Case Mapping

   The casemapping rule MUST be specified by each application protocol
   that uses or subclasses the NameClass.

3.1.6.  Normalization

   The normalization form MUST be specified by each application protocol
   that uses or subclasses the NameClass.

   However, in accordance with [RFC5198], normalization form C (NFC) is
   RECOMMENDED.

3.2.  FreeClass

   Some application technologies need a special class of strings that
   can be used in a free-form way, e.g., as a passphrase in an
   authentication exchange (see [I-D.melnikov-precis-saslprepbis] or a
   nickname in a chatroom (see [I-D.saintandre-precis-nickname]).  We
   group such things into a bucket called "FreeClass" having the
   following features.

   NOTE: Consult Section 10.6 for relevant security considerations when
   strings conforming to the FreeClass, or a subclass thereof, are used
   as passwords or passphrases.

3.2.1.  Valid

   o  Traditional letters and numbers, i.e., the LetterDigits ("A")
      category first defined in [RFC5892] and listed here under
      Section 6.1.

Internet-Draft              PRECIS Framework                    May 2012


   o  Additional letters and numbers, i.e., the OtherLetterDigits ("R")
      category defined under Section 6.18.
   o  Code points in the range U+0021 through U+007E, i.e., the ASCII7
      ("K") rule defined under Section 6.11.
   o  Any character that has a compatibility equivalent, i.e., the
      HasCompat ("Q") category defined under Section 6.17.
   o  Space characters, i.e., the Spaces ("N") category defined under
      Section 6.14.
   o  Symbol characters, i.e., the Symbols ("O") category defined under
      Section 6.15.
   o  Punctuation characters, i.e., the Punctuation ("P") category
      defined under Section 6.16.
   o  Letters and digits other than the "traditional" letters and digits
      allowed in IDNs, i.e., the OtherLetterDigits ("R") category
      defined under Section 6.18.

3.2.2.  Disallowed

   o  Control characters, i.e., the Controls ("L") category defined
      under Section 6.12.
   o  Ignorable characters, i.e., the PrecisIgnorableProperties ("M")
      category defined under Section 6.13.

3.2.3.  Unassigned

   Any code points that are not yet assigned in the Unicode character
   set SHALL be considered Unassigned for purposes of the FreeClass.

3.2.4.  Directionality

   The directionality rule MUST be specified by each application
   protocol that uses or subclasses the FreeClass.

3.2.5.  Case Mapping

   The casemapping rule MUST be specified by each application protocol
   that uses or subclasses the FreeClass.

   In general, case preservation is NOT RECOMMENDED for application
   protocols that perform case-insensitive comparison of
   internationalized strings; instead, application protocols SHOULD
   either (a) not preserve case but perform case-insensitive matching or
   (b) preserve case but perform case-sensitive comparison.

   In order to maximize entropy, it is NOT RECOMMENDED for application
   protocols to map uppercase and titlecase code points to their
   lowercase equivalents when strings conforming to the FreeClass, or a
   subclass thereof, are used in passwords or passphrases; instead, it

Internet-Draft              PRECIS Framework                    May 2012


   is RECOMMENDED to preserve the case of all code points contained in
   such strings.

3.2.6.  Normalization

   The normalization form MUST be specified by each application protocol
   that uses or subclasses the FreeClass.

   However, in accordance with [RFC5198], normalization form C (NFC) is
   RECOMMENDED.


4.  Use of PRECIS String Classes

4.1.  Principles

   This document defines the valid, disallowed, and unassigned rules.
   Application protocols that use the PRECIS string classes MUST define
   the directionality, casemapping, and normalization rules.  Such
   definitions MUST at a minimum specify the following:

   Directionality:  Whether any instance of the class that contains a
      right-to-left code point is to be considered a right-to-left
      string, or whether some other rule is to be applied (e.g., the
      "Bidi Rule" from [RFC5893]).

   Casemapping:  Whether uppercase and titlecase code points are to be
      (a) preserved or (b) mapped to lowercase.

   Normalization:  Which Unicode normalization form (D, KD, C, or KC) is
      to be applied (see [UAX15] for background information); in
      accordance with [RFC5198], NFC is RECOMMENDED.

4.2.  Subclassing

   Application protocols are allowed to subclass the base string classes
   specified in this document.  As the word "subclass" implies, a
   subclass MUST NOT add as valid any code points or character
   categories that are disallowed by the base string class.  However, a
   subclass MAY do either of the following:

   1.  Exclude specific code points that are included in the base string
       class.
   2.  Exclude characters matching certain Unicode properties (e.g.,
       math symbols) that are included in the base string class.

Internet-Draft              PRECIS Framework                    May 2012


4.3.  Registration

   Application protocols that use the PRECIS string classes MUST
   register with the IANA as described under Section 9.2.  This is
   especially important for protocols that subclass the PRECIS string
   classes.


5.  Code Point Properties

   In order to implement the string classes described above, this
   document does the following:

   1.  Reviews and classifies the collections of code points in the
       Unicode character set by examining various code point properties.

   2.  Defines an algorithm for determining a derived property value,
       which can vary depending on the string class being used by the
       relevant application protocol.

   This document is not intended to specify precisely how derived
   property values are to be applied in protocol strings.  That
   information should be defined in the protocol specification that uses
   or subclasses a base string class from this document.

   The value of the property is to be interpreted as follows.

   PROTOCOL VALID  Those code points that are allowed to be used in any
      PRECIS string class (NameClass and FreeClass).  Code points with
      this property value are permitted for general use in any string
      class.  The abbreviated term PVALID is used to refer to this value
      in the remainder of this document.

   SPECIFIC CLASS PROTOCOL VALID  Those code points that are allowed to
      be used in specific string classes.  Code points with this
      property value are permitted for use in specific string classes.
      In the remainder of this document, the abbreviated term *_PVAL is
      used, where * = (NAME | FREE), i.e., either FREE_PVAL or
      NAME_PVAL.

   CONTEXTUAL RULE REQUIRED  Some characteristics of the character, such
      as its being invisible in certain contexts or problematic in
      others, require that it not be used in labels unless specific
      other characters or properties are present.  The abbreviated term
      CONTEXT is used to refer to this value in the remainder of this
      document.  There are two subdivisions of CONTEXTUAL RULE REQUIRED,
      the first for Join_controls (called CONTEXTJ) and the second for
      other characters (called CONTEXTO).



Saint-Andre & Blanchet  Expires November 11, 2012              [Page 11]

Internet-Draft              PRECIS Framework                    May 2012


   DISALLOWED  Those code points that must not be included in any string
      class.  Code points with this property value are not permitted in
      any string class.

   SPECIFIC CLASS DISALLOWED  Those code points that are not to be
      included in a specific string class.  Code points with this
      property value are not permitted in one of the string classes but
      might be permitted in others.  In the remainder of this document,
      the abbreviated term *_DIS is used, where * = (NAME | FREE), i.e.,
      either FREE_DIS or NAME_DIS.

   UNASSIGNED  Those code points that are not designated (i.e. are
      unassigned) in the Unicode Standard.

   The mechanisms described here allow determination of the value of the
   property for future versions of Unicode (including characters added
   after Unicode 5.2 or 6.1 depending on the category, since some
   categories in this document are reused from IDNA2008 and therefore
   were defined at the time of Unicode 5.2).  Changes in Unicode
   properties that do not affect the outcome of this process do not
   affect this framework.  For example, a character can have its Unicode
   General_Category value [UNICODE] change from So to Sm, or from Lo to
   Ll, without affecting the algorithm results.  Moreover, even if such
   changes were to result, the BackwardCompatible list (Section 6.7) can
   be adjusted to ensure the stability of the results.

   Some code points need to be allowed in exceptional circumstances, but
   should be excluded in all other cases; these rules are also described
   in other documents.  The most notable of these are the Join Control
   characters, U+200D ZERO WIDTH JOINER and U+200C ZERO WIDTH NON-
   JOINER.  Both of them have the derived property value CONTEXTJ.  A
   character with the derived property value CONTEXTJ or CONTEXTO
   (CONTEXTUAL RULE REQUIRED) is not to be used unless an appropriate
   rule has been established and the context of the character is
   consistent with that rule.  It is invalid to generate a string
   containing these characters unless such a contextual rule is found
   and satisfied.  PRECIS does not define its own contextual rules, but
   instead re-uses the contextual rules defined for IDNA2008; please see
   Appendix A of [RFC5892] for more information.


6.  Category Definitions Used to Calculate Derived Property Value

   The derived property obtains its value based on a two-step procedure:

   1.  Characters are placed in one or more character categories either
       (1) based on core properties defined by the Unicode Standard or
       (2) by treating the code point as an exception and addressing the



Saint-Andre & Blanchet  Expires November 11, 2012              [Page 12]

Internet-Draft              PRECIS Framework                    May 2012


       code point as its code point value.  These categories are not
       mutually exclusive.

   2.  Set operations are used with these categories to determine the
       values for a property that is specific to a given string class.
       These operations are specified under Section 7.

   (NOTE: Unicode property names and property value names might have
   short abbreviations, such as "gc" for the General_Category property
   and "Ll" for the Lowercase_Letter property value of the gc property.)

   In the following specification of character categories, the operation
   that returns the value of a particular Unicode character property for
   a code point is designated by using the formal name of that property
   (from the Unicode PropertyAliases.txt [1]) followed by '(cp)' for
   "code point".  For example, the value of the General_Category
   property for a code point is indicated by General_Category(cp).

   The first ten categories (A-J) shown below were previously defined
   for IDNA2008 and are copied directly from [RFC5892].  Some of these
   categories are reused in PRECIS and some of them are not; however,
   the lettering of categories is retained to prevent overlap and to
   ease implementation of both IDNA2008 and PRECIS in a single software
   application.  The next seven categories (K-Q) are specific to PRECIS.

6.1.  LetterDigits (A)

   NOTE: This category is defined in [RFC5892] and copied here for use
   in PRECIS.

   A: General_Category(cp) is in {Ll, Lu, Lm, Lo, Mn, Mc, Nd}

   These rules identify characters commonly used in mnemonics and often
   informally described as "language characters".

   For more information, see section 4.5 of [UNICODE].

   The categories used in this rule are:
   o  Ll - Lowercase_Letter
   o  Lu - Uppercase_Letter
   o  Lm - Modifier_Letter
   o  Lo - Other_Letter
   o  Mn - Nonspacing_Mark
   o  Mc - Spacing_Mark
   o  Nd - Decimal_Number

6.3.  IgnorableProperties (C)

   NOTE: This category is defined in [RFC5892] but not used in PRECIS.
   See the "PrecisIgnorableProperties (M)" category below for a more
   inclusive category used in PRECIS identifiers.

6.4.  IgnorableBlocks (D)

   NOTE: This category is defined in [RFC5892] but not used in PRECIS.

6.5.  LDH (E)

   NOTE: This category is defined in [RFC5892] but not used in PRECIS.
   See the "ASCII7 (K)" category below for a more inclusive category
   used in PRECIS identifiers.

6.6.  Exceptions (F)

   NOTE: This category is defined in [RFC5892] and used in PRECIS to
   ensure consistent treatment of the relevant code points.

   F: cp is in {00B7, 00DF, 0375, 03C2, 05F3, 05F4, 0640, 0660,
                0661, 0662, 0663, 0664, 0665, 0666, 0667, 0668,
                0669, 06F0, 06F1, 06F2, 06F3, 06F4, 06F5, 06F6,
                06F7, 06F8, 06F9, 06FD, 06FE, 07FA, 0F0B, 3007,
                302E, 302F, 3031, 3032, 3033, 3034, 3035, 303B,
                30FB}

   This category explicitly lists code points for which the category
   cannot be assigned using only the core property values that exist in
   the Unicode standard.  The values are according to the table below:

   PVALID -- Would otherwise have been DISALLOWED

   00DF; PVALID     # LATIN SMALL LETTER SHARP S

6.7.  BackwardCompatible (G)

   NOTE: This category is defined in [RFC5892] and copied here for use
   in PRECIS.  Because of how the PRECIS string classes are defined,
   only changes that would result in code points being added to or
   removed from the LetterDigits ("A") category would result in

   backward-incompatible modifications to code point assignments.
   Therefore, management of this category is handled via the processes
   specified in [RFC5892].

   G: cp is in {}

   This category includes the code points for which property values in
   versions of Unicode after 5.2 have changed in such a way that the
   derived property value would no longer be PVALID or DISALLOWED.  If
   changes are made to future versions of Unicode so that code points
   might change property value from PVALID or DISALLOWED, then this
   table can be updated and keep special exception values so that the
   property values for code points stay stable.

6.8.  JoinControl (H)

   NOTE: This category is defined in [RFC5892] and copied here for use
   in PRECIS.

   H: Join_Control(cp) = True

   This category consists of Join Control characters (i.e., they are not
   in LetterDigits (Section 6.1)) but are still required in strings
   under some circumstances.

6.9.  OldHangulJamo (I)

   NOTE: This category is defined in [RFC5892] and copied here for use
   in PRECIS.

   I: Hangul_Syllable_Type(cp) is in {L, V, T}

   This category consists of all conjoining Hangul Jamo (Leading Jamo,
   Vowel Jamo, and Trailing Jamo).

   Elimination of conjoining Hangul Jamos from the set of PVALID
   characters results in restricting the set of Korean PVALID characters
   just to preformed, modern Hangul syllable characters.  Old Hangul
   syllables, which must be spelled with sequences of conjoining Hangul
   Jamos, are not PVALID for string classes.

6.10.  Unassigned (J)

   NOTE: This category is defined in [RFC5892] and copied here for use
   in PRECIS.

   J: General_Category(cp) is in {Cn} and
      Noncharacter_Code_Point(cp) = False

Internet-Draft              PRECIS Framework                    May 2012


   This category consists of code points in the Unicode character set
   that are not (yet) assigned.  It should be noted that Unicode
   distinguishes between 'unassigned code points' and 'unassigned
   characters'.  The unassigned code points are all but (Cn -
   Noncharacters), while the unassigned *characters* are all but (Cn +
   Cs).

6.11.  ASCII7 (K)

   This PRECIS-specific category exempts most characters in the ASCII-7
   range from other rules that might be applied during PRECIS
   processing, on the assumption that these code points are in such wide
   use that disallowing them would be counter-productive.

   K: cp is in {0021..007E}

6.12.  Controls (L)

   L: Control(cp) = True

6.13.  PrecisIgnorableProperties (M)

   This PRECIS-specific category is used to group code points that are
   not recommended for use in PRECIS string classes.

   M: Default_Ignorable_Code_Point(cp) = True or
      Noncharacter_Code_Point(cp) = True

   The definition for Default_Ignorable_Code_Point can be found in the
   DerivedCoreProperties.txt [2] file, and at the time of Unicode 6.1 is
   as follows:

     Other_Default_Ignorable_Code_Point
   + Cf (Format characters)
   + Variation_Selector
   - White_Space
   - FFF9..FFFB (Annotation Characters)
   - 0600..0604, 06DD, 070F, 110BD (exceptional Cf characters
                                    that should be visible)

6.14.  Spaces (N)

   This PRECIS-specific category is used to group code points that are
   space characters.

   N: General_Category(cp) is in {Zs}

6.15.  Symbols (O)

   This PRECIS-specific category is used to group code points that are
   symbols.

   O: General_Category(cp) is in {Sm, Sc, Sk, So}

6.16.  Punctuation (P)

   This PRECIS-specific category is used to group code points that are
   punctuation characters.

   P: General_Category(cp) is in {Pc, Pd, Ps, Pe, Pi, Pf, Po}

6.17.  HasCompat (Q)

   This PRECIS-specific category is used to group code points that have
   compatibility equivalents as explained in Chapter 2 and Chapter 3 of
   [UNICODE].

   Q: toNFKC(cp) != cp

   The toNFKC() operation returns the code point in normalization form
   KC.  For more information, see Section 5 of [UAX15].

6.18.  OtherLetterDigits (R)

   This PRECIS-specific category is used to group code points that are
   letters and digits other than the traditional letters and digits
   grouped under the LetterDigits (A) class (see Section 6.1).

   R: General_Category(cp) is in {Lt, Nl, No, Me}


7.  Calculation of the Derived Property

   Possible values of the derived property are:

   o  PVALID
   o  NAME_PVAL
   o  FREE_PVAL
   o  CONTEXTJ
   o  CONTEXTO
   o  DISALLOWED
   o  NAME_DIS
   o  FREE_DIS

Internet-Draft              PRECIS Framework                    May 2012


   o  UNASSIGNED

   NOTE: The value of the derived property calculated can depend on the
   string class; for example, if an identifier used in an application
   protocol is defined as using or subclassing the PRECIS NameClass then
   a space character such as U+0020 would be assigned to NAME_DIS,
   whereas if an identifier is defined as using or subclassing the
   PRECIS FreeClass then the character would be assigned to FREE_PVAL.

   The algorithm to calculate the value of the derived property is as
   follows.  (NOTE: Use of the name of a rule (such as "Exception")
   implies the set of code points that the rule defines, whereas the
   same name as a function call (such as "Exception(cp)") implies the
   value that the code point has in the Exceptions table.)

   If .cp. .in. Exceptions Then Exceptions(cp);
   Else If .cp. .in. BackwardCompatible Then BackwardCompatible(cp);
   Else If .cp. .in. Unassigned Then UNASSIGNED;
   Else If .cp. .in. ASCII7 Then PVALID;
   Else If .cp. .in. JoinControl Then CONTEXTJ;
   Else If .cp. .in. PrecisIgnorableProperties Then DISALLOWED;
   Else If .cp. .in. Controls Then DISALLOWED;
   Else If .cp. .in. OldHangulJamo Then DISALLOWED;
   Else If .cp. .in. LetterDigits Then PVALID;
   Else If .cp. .in. OtherLetterDigits Then NAME_DIS or FREE_PVAL;
   Else If .cp. .in. Spaces Then NAME_DIS or FREE_PVAL;
   Else If .cp. .in. Symbols Then NAME_DIS or FREE_PVAL;
   Else If .cp. .in. Punctuation Then NAME_DIS or FREE_PVAL;
   Else If .cp. .in. HasCompat Then NAME_DIS or FREE_PVAL;
   Else DISALLOWED;


8.  Code Points

   The Categories and Rules defined in Section 6 and Section 7 apply to
   all Unicode code points.  The table in Appendix A shows, for
   illustrative purposes, the consequences of the categories and
   classification rules, and the resulting property values.

   The list of code points that can be found in Appendix A is non-
   normative.  Instead, the rules defined by Section 6 and Section 7 are
   normative, and any tables are derived from the rules.


9.  IANA Considerations

Internet-Draft              PRECIS Framework                    May 2012


9.1.  PRECIS Derived Property Value Registry

   IANA is requested to create a PRECIS-specific registry with the
   Derived Properties for the versions of Unicode that are released
   after (and including) version 6.1.  The derived property value is to
   be calculated in cooperation with a designated expert [RFC5226]
   according to the specifications in Section 6 and Section 7, and not
   by copying the non-normative table found in Appendix A.

   If during this process (creation of the table of derived property
   values) followed by a designated expert review, either backward-
   incompatible changes to the table of derived properties are
   discovered, or otherwise problems arise during the creation of the
   table, that is to be flagged to the IESG.  Changes to the rules (as
   specified in Section 6 and Section 7) require IETF Review, as
   described in [RFC5226].

9.2.  PRECIS Usage Registry

   IANA is requested to create a registry of application protocols that
   use the base string classes.  The registry will include one entry for
   each use (e.g., if a protocol uses both the NameClass and the
   FreeClass then the specification for that protocol would submit two
   registrations).  In accordance with [RFC5226], the registration
   policy is "First Come First Served".

   The registration template is as follows:

   Application Protocol:  [the application protocol that is using or
      subclassing the PRECIS string class]
   Base Class:  [which base class is being used]
   Subclassing:  [whether the base class is being subclassed and, if so,
      where documentation of the subclassing can be found]
   Directionality:  [the behavioral rule for handling of right-to-left
      code points]
   Casemapping:  [the behavioral rule for handling of case]
   Normalization:  [which Unicode normalization form is applied]
   Specification:  [a pointer to relevant documentation, such as an RFC
      or Internet-Draft]


10.  Security Considerations

10.1.  General Issues

   The security of applications that use this framework can depend in
   part on the proper preparation and comparison of internationalized
   strings.  For example, such strings can be used to make



Saint-Andre & Blanchet  Expires November 11, 2012              [Page 20]

Internet-Draft              PRECIS Framework                    May 2012


   authentication and authorization decisions, and the security of an
   application could be compromised if an entity providing a given
   string is connected to the wrong account or online resource based on
   different interpretations of the string.

   Specifications of application protocols that use this framework are
   encouraged to describe how internationalized strings are used in the
   protocol, including the security implications of any false positives
   and false negatives that might result from various comparison
   operations.  For some helpful guidelines, refer to
   [I-D.iab-identifier-comparison], [RFC5890], [UTR36], and [UTR39].

10.2.  Use of the NameClass

   Strings that conform to the NameClass and any subclass thereof are
   intended to be relatively safe for use in a broad range of
   applications, primarily because they include only letters, digits,
   and "grandfathered" non-space characters from the US-ASCII range and
   thus exclude spaces, characters with compatibility equivalents, and
   almost all symbols and punctuation marks.  However, such strings can
   still include so-called confusable characters (see Section 10.5;
   therefore protocol designers and implementers are encouraged to pay
   close attention to the security considerations described elsewhere in
   this document.

10.3.  Use of the FreeClass

   Strings that conform to the FreeClass and many subclasses thereof can
   include virtually any Unicode character.  This makes the FreeClass
   quite expressive, but also problematic from the perspective of
   possible user confusion.  Protocol designers are hereby warned that
   the FreeClass contains codepoints they might not understand, and are
   encouraged to use or subclass the NameClass wherever feasible;
   however, if an application protocol requires more code points than
   are allowed by the NameClass (e.g., to allow ASCII space in human
   names), protocol designers are encouraged to define a subclass of the
   FreeClass that restricts the allowable code points as tightly as
   possible.  (The working group considered the option of allowing
   superclasses as well as subclasses of PRECIS string classes, but
   decided against allowing superclasses to reduce the likelihood of
   security and interoperability problems.)

10.4.  Local Character Set Issues

   When systems use local character sets other than ASCII and Unicode,
   these specifications leave the problem of converting between the
   local character set and Unicode up to the application or local
   system.  If different applications (or different versions of one

Internet-Draft              PRECIS Framework                    May 2012


   application) implement different rules for conversions among coded
   character sets, they could interpret the same name differently and
   contact different application servers or other network entities.
   This problem is not solved by security protocols, such as Transport
   Layer Security (TLS) [RFC5246] and the Simple Authentication and
   Security Layer (SASL) [RFC4422], that do not take local character
   sets into account.

10.5.  Visually Similar Characters

   Some characters are visually similar and thus can cause confusion
   among humans.  Such characters are often called "confusable
   characters" or "confusables".

   The problem of confusable characters is not necessarily caused by the
   use of Unicode code points outside the US-ASCII range.  For example,
   in some presentations and to some individuals the string "ju1iet"
   (spelled with the Arabic numeral one as the third character) might
   appear to be the same as "juliet" (spelled with the lowercase version
   of the letter "L"), especially on casual visual inspection.  This
   phenomenon is sometimes called "typejacking".

   However, the problem is made more serious by introducing the full
   range of Unicode code points into protocol strings.  For example, the
   characters U+13DA U+13A2 U+13B5 U+13AC U+13A2 U+13AC U+13D2 from the
   Cherokee block look similar to the US-ASCII characters "STPETER" as
   they might look when presented in a "creative" font.

   In some examples of confusable characters, it is unlikely that the
   average human could tell the difference between the real string and
   the fake string.  (Indeed, there is no programmatic way to
   distinguish with full certainty which is the fake string and which is
   the real string; in some contexts, the string formed of Cherokee
   characters might be the real string and the string formed of US-ASCII
   characters might be the fake string.)  Because PRECIS-compliant
   strings can contain almost any properly encoded Unicode code point,
   it can be relatively easy to fake or mimic some strings in systems
   that use the PRECIS framework.  The fact that some strings are easily
   confused introduces security vulnerabilities of the kind that have
   also plagued the World Wide Web, specifically the phenomenon known as
   phishing.

   Despite the fact that some specific suggestions about identification
   and handling of confusable characters appear in the Unicode Security
   Considerations [UTR36], it is also true (as noted in [RFC5890]) that
   "there are no comprehensive technical solutions to the problems of
   confusable characters".  Because it is impossible to map visually
   similar characters without a great deal of context (such as knowing



Saint-Andre & Blanchet  Expires November 11, 2012              [Page 22]

Internet-Draft              PRECIS Framework                    May 2012


   the fonts used), the PRECIS framework does nothing to map similar-
   looking characters together, nor does it prohibit some characters
   because they look like others.

   However, specifications for application protocols that use this
   framework MUST describe how confusable characters can be used to
   compromise the security of systems that use the protocol in question,
   and any protocol-specific suggestions for overcoming those threats.
   In particular, software implementations and service deployments that
   use PRECIS-based technologies are strongly encouraged to define and
   implement consistent policies regarding the registration, storage,
   and presentation of visually similar characters.  The following
   recommendations are appropriate:

   1.  An application service SHOULD define a policy that specifies the
       scripts or blocks of characters that the service will allow to be
       registered (e.g., in an account name) or stored (e.g., in a file
       name).  Such a policy SHOULD be informed by the languages and
       scripts that are used to write registered account names; in
       particular, to reduce confusion, the service SHOULD forbid
       registration or storage of stings that contain characters from
       more than one script and to restrict registrations to characters
       drawn from a very small number of scripts (e.g., scripts that are
       well-understood by the administrators of the service, to improve
       manageability).

   2.  User-oriented application software SHOULD define a policy that
       specifies how internationalized strings will be presented to a
       human user.  Because every human user of such software has a
       preferred language or a small set of preferred languages, the
       software SHOULD gather that information either explicitly from
       the user or implicitly via the operating system of the user's
       device.  Furthermore, because most languages are typically
       represented by a single script or a small set of scripts, and
       because and most scripts are typically contained in one or more
       blocks of characters, the software SHOULD warn the user when
       presenting a string that mixes characters from more than one
       script or block, or that uses characters outside the normal range
       of the user's preferred language(s).  (Such a recommendation is
       not intended to discourage communication across different
       communities of language users; instead, it recognizes the
       existence of such communities and encourages due caution when
       presenting unfamiliar scripts or characters to human users.)

10.6.  Security of Passwords and Passphrases

   One goal of passwords and passphrases is to maximize the amount of
   entropy, for example by allowing a wide range of code points and by



Saint-Andre & Blanchet  Expires November 11, 2012              [Page 23]

Internet-Draft              PRECIS Framework                    May 2012


   ensuring that secrets are not prepared in such a way that code points
   are compared aggressively.  Therefore, it is NOT RECOMMENDED for
   application protocols to subclass the FreeClass for use in passwords
   and passphrases in a way that removes entire categories (e.g., by
   disallowing symbols or punctuation).  Furthermore, it is NOT
   RECOMMENDED for application protocols to map uppercase and titlecase
   code points to their lowercase equivalents in such strings; instead,
   it is RECOMMENDED to preserve the case of all code points contained
   in such strings.

   That said, software implementers need to be aware that there exist
   tradeoffs between entropy and usability.  For example, allowing a
   user to establish a password containing "uncommon" code points might
   make it difficult for the user to access an application when using an
   unfamiliar or constrained input device.

   Some application protocols use passwords and passphrases directly,
   whereas others reuse technologies that themselves process passwords
   (one example is the Simple Authentication and Security Layer
   [RFC4422]).  Moreover, passwords are often carried by a sequence of
   protocols with backends authentication systems or data storage
   systems such as RADIUS [RFC2865] and LDAP [RFC4510].  Developers of
   application protocols are encouraged to look into reusing these
   profiles instead of defining new ones, so that end-user expectations
   about passwords are consistent no matter which application protocol
   is used.


11.  Interoperability Considerations

   Although strings that are consumed in PRECIS-based application
   protocols are often encoded using UTF-8 [RFC3629], the exact encoding
   is a matter for the application protocol that reuses PRECIS, not for
   the PRECIS framework.

   It is known that some existing systems are unable to support the full
   Unicode character set, or even any characters outside the US-ASCII
   range.  If two (or more) applications need to interoperate when
   exchanging data (e.g., for the purpose of authenticating a username
   or password), they will naturally need have in common at least one
   coded character set (as defined by [RFC6365]).  Establishing such a
   baseline is a matter for the application protocol that reuses PRECIS,
   not for the PRECIS framework.
