To give your library a sense of unity, I'd rename initState() → rc4InitState() and crypt() → rc4Crypt().The latter renaming is also important so as not to clash with the traditional … WebRC6. In cryptography, RC6 is a symmetric key block cipher derived from RC5. It was designed by Ron Rivest, Matt Robshaw, Ray Sidney, and Yiqun Lisa Yin to meet the requirements of the Advanced Encryption Standard (AES) competition. The algorithm was one of the five finalists, and was also submitted to the NESSIE and CRYPTREC projects.
