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.
