1.  Introduction

   The RC4 [RC4] algorithm is a widely used stream cipher.  Test vectors
   for algorithms are useful for implementers.  The RC4 cipher can use
   different key lengths.  Advances in crypto-analysis [FMcG] [MANTIN01]
   [MIRONOV] [MANTIN05] suggest that initial parts of the stream output
   need to be discarded.  This document contains several test vectors
   for different key lengths and for different offsets in the stream.

   Motivation for this document arose from the implementation of
   [RFC4345].

   The test vectors provided in this document have been collected by
   generating RC4 keystream output from three separate implementations
   and comparing the streams.  The RC4 implementations used are
   Libgcrypt 1.4.4 [LIBGCRYPT], Nettle 2.0 [NETTLE], and a custom
   implementation.

   The document contains test vectors for two different keys:

   Key 1:  The key byte index (starting on one), that is: 0x01, 0x02,
      0x03, 0x04,...

   Key 2:  Generated by hashing the string "Internet Engineering Task
      Force" with the SHA-256 [SHS] [RFC4634] hash function, using the
      following command:

      $ echo -n "Internet Engineering Task Force" | sha256sum
      1ada31d5cf688221c109163908ebe51debb46227c6cc8b37641910833222772a

   The generated string has also been verified using the SHA-256 hash
   function implementation in OpenSSL (versions 0.9.8l and 1.0.0a)
   [OPENSSL].

   The digest that is generated is then truncated to the appropriate
   length, keeping the Least Significant Bit (LSB) part of the digest as
   the key.

   The key lengths used in this document are 40, 56, 64, 80, 128, 192,
   and 256 bits, respectively.  The stream offsets used in this document
   are 0, 256, 512, 768, 1024, 1536, 2048, 3072, and 4096 bytes,
   respectively.  Offset 1536 corresponds to recommendations in
   [RFC4345].  The offsets 768 and 3072 correspond to recommendations in
   [SANS].

3.  Security Considerations

   The RC4 algorithm does not meet the basic criteria required for an
   encryption algorithm, as its output is distinguishable from random.
   The use of RC4 continues to be recommended against; in particular,
   its use in new specifications is discouraged.  This note is intended
   only to aid the interoperability of existing specifications that make
   use of RC4.
