19 This module XS implementation of the RC4 algorithm, developed by RSA
20 Security, Inc. Here is the description from Wikipedia website:
21
22 In cryptography, RC4 (also known as ARC4 or ARCFOUR meaning Alleged
23 RC4, see below) is the most widely-used software stream cipher and is
24 used in popular protocols such as Secure Sockets Layer (SSL) (to
25 protect Internet traffic) and WEP (to secure wireless networks). While
26 remarkable for its simplicity and speed in software, RC4 is vulnerable
27 to attacks when the beginning of the output keystream is not discarded,
28 or a single keystream is used twice; some ways of using RC4 can lead to
29 very insecure cryptosystems such as WEP.
