WebRC4 was designed by Ron Rivest of RSA Security in 1987. While it is officially termed "Rivest Cipher 4", the RC acronym is alternatively understood to stand for "Ron's Code" [9] (see also RC2, RC5 and RC6 ). RC4 was initially a trade secret, but in September 1994, a description of it was anonymously posted to the Cypherpunks mailing list. [10] WebThe RC5 is basically denoted as RC5-w/r/b where w=word size in bits, r=number of rounds, b=number of 8-bit bytes in the key. Algorithm[edit] RC5 encryption and decryption both expand the random key into 2(r+1) words that will be used sequentially (and only once each) during the encryption and decryption processes.
