ARC4 128bit.
ARC4 is short for `Alleged RC4'. The real RC4 algorithm is proprietary to RSA Data Security Inc.
In September 1994, someone posted C code to both the Cypherpunks mailing list and to the Usenet
newsgroup @code{sci.crypt}, claiming that it implemented the RC4 algorithm.
This posted code is what it being called Alleged RC4, or ARC4 for short.
ARC4 is a private-key cipher; the same key is used to both encrypt and decrypt.
