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.
