1.  Introduction

The RC4 (Schneier, B., “Applied Cryptography, second edition, section 17.1, page 397,” .) [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] (Fluhrer, S. and D. McGrew, “Statistical Analysis of the Alleged RC4 Keystream Generator,” .) [MANTIN01] (Mantin, I., “Analysis of the Stream Cipher RC4,” .) [MIRONOV] (Mantin, I., “(Not So) Random Shuffles of RC4,” .) [MANTIN05] (Mantin, I., “Predicting and Distinguishing Attacks on RC4 Keystream Generator,” .) suggests that initial parts of the stream output needs 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 implementation of [RFC4345] (Harris, B., “Improved Arcfour Modes for the Secure Shell (SSH) Transport Layer Protocol,” January 2006.).

The test vectors provided in this document has been collected by generating keystream output from three separate implementations and comparing the streams: Libgcrypt 1.4.4 [LIBGCRYPT] (Koch, W., “Libgcrypt, version 1.4.4,” .), Nettle [NETTLE] (Möller, N., “Nettle, version 2.0,” .), 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 [FIPS.180‑2.2002] (National Institute of Standards and Technology, “Secure Hash Standard,” August 2002.) [RFC4634] (Eastlake, D. and T. Hansen, “US Secure Hash Algorithms (SHA and HMAC-SHA),” July 2006.) 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 function implemented by OpenSSL 0.9.8l.

The digest generated is then truncated to the appropriate length, keeping the LSB part of the digest as 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 [RFC4345] (Harris, B., “Improved Arcfour Modes for the Secure Shell (SSH) Transport Layer Protocol,” January 2006.). And the offsets 768 and 3072 corresponds to recommendations by [SANS] (Hopwood, D., “Standard Cryptographic Algorithm Naming (SANS) entry on RC4,” .).

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 continue 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.
