- Crypt::RC4 is a simple implementation of the RC4 algorithm, developed by
- RSA Security, Inc. Here is the description from RSA's website:
- RC4 is a stream cipher designed by Rivest for RSA Data Security (now RSA
- Security). It is a variable key-size stream cipher with byte-oriented
- operations. The algorithm is based on the use of a random permutation.
- Analysis shows that the period of the cipher is overwhelmingly likely to be
- greater than 10100. Eight to sixteen machine operations are required per
- output byte, and the cipher can be expected to run very quickly in software.
- Independent analysts have scrutinized the algorithm and it is considered
- secure.
