It was developed in 1987 by Ron Rivest, one of the developers of the public-key cipher RSA. RC4 is a trademark. RC2, RC5, and RC6 are symmetric-key block ciphers. RC4 does not generate its keystream by using a LFSR. For RC4, stream combinations are done on byte-length strings of plaintext. crystal name clip art
