What kind of cipher is included in mcrypt?

Although the source code is now available RC4 is trademarked by RSADSI so a compatible cipher named ARCFOUR is included in the mcrypt distribution. It is a stream cipher and has a maximum key of 2048 bits. RC6: RC6 was designed by Ron Rivest for RSA labs. In mcrypt it uses block size of 128 bit and a key size of 128/192/256 bits.
