Internet-Draft        Additional S/MIME Capabilities      December 2009


Abstract

   This document lists values for the S/MIME Capabilities Attribute.
   The attribute itself is defined in RFC TBD1, but the values for each
   are defined in separate algorithm documents and in some cases not at
   all.  The SMIME Capability values can be included in S/MIME messages
   as a signed attribute and in public key certificates as an extension.

   //RFC EDITOR: Replace TBD1 with the # assigned to draft-ietf-smime-
   3851bis-10.txt.

1. Introduction

   There has been and continues to be some confusion about an
   algorithm's parameter values.  RFCs that define how an algorithm is
   used with CMS also define the algorithm's parameter values, e.g.,
   [RFC3370].  Additionally, these RFCs should define the
   SMIMECapabilities attribute values; however, some have failed to do
   so and some have failed to do so correctly.  Now, the situation may
   exist where implementations emit SMIMECapabilities attribute values
   that are the same as algorithm's parameters when used in CMS instead
   of following the SMIMECapablities requirements from [RFCTBD1]: in
   "the event that there are no differentiating parameters for a
   particular OID, the parameters MUST be omitted, and MUST NOT be
   encoded as NULL." For example, ECDSA with SHA-1 from [RFCTBD3]
   includes NULL parameters when they should have been omitted.

   //RFC EDITOR: Replace TBD3 with the # assigned to draft-ietf-smime-
   3278bis-07.txt.

   This document lists values for the S/MIME Capabilities Attribute.
   The attribute itself is defined in [RFCTBD1], but the values for each
   are defined in separate algorithm documents and in some cases not at
   all. Capability values can be included in S/MIME messages as an
   attribute and in public key certificates as an extension [RFC4262].

   The majority of the values in this document are defined in other
   documents, and this document references those documents before the
   SMIME Capability.  Values are encoded using the Distinguished
   Encoding Rule (DER) [X.690] and are a sequence of algorithm object
   identifier plus any parameters.  The values provided in this document
   are values for one algorithm parameter pair.  The syntax for the
   attribute is as follows and is included for convenience:

     SMIMECapabilities ::= SEQUENCE OF SMIMECapability

Internet-Draft        Additional S/MIME Capabilities      December 2009


     SMIMECapability ::= SEQUENCE {
       capabilityID OBJECT IDENTIFIER,
       parameters ANY DEFINED BY capabilityID OPTIONAL }

   As specified in [RFCTBD1]: "the object identifiers (OIDs) are listed
   in order of their preference, but SHOULD be separated logically along
   the lines of their categories (signature algorithms, symmetric
   algorithms, key encipherment algorithms, etc.)"  As the "structure of
   the SMIMECapabilities attribute is [designed] to facilitate simple
   table lookups and binary comparisons in order to determine matches",
   the values are given in encoded format.

   The DER [X.690] values for the capabilities are preceded by the
   algorithm's name and if they were previously defined a reference for
   the document in which they are defined.

1.1. Requirements Terminology

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

2. Message Digest Algorithms

   [RFC3370] and [RFCTBD2] define the following message digest
   algorithms for use with CMS:

   MD5: 300a 0608 2a86 4886 f70d 0205

   NOTE: Though [RFC3370] allows NULL parameters for SHA-1, SHA-224,
   SHA-256, SHA-384, SHA-512, parameters MUST NOT be included as per
   [RFCTBD1] because there is no differentiating parameters for SHA-1
   (e.g., output length).

3. Digital Signature Algorithms

   [RFC3370], [RFC4056], [RFCTBD2], and [RFCTBD3] define the following
   digital signature algorithms for use with CMS:

   NOTE: [RFCTBD3] shows the ECDSA with SHA-1 with NULL parameter
   values, but the NULL parameters should not have been included
   according to [RFCTBD1].  The NULL is retained for backwards
   compatibility.
