RC5 encryption algorithm is a new fast symmetric block cipher
developed by Ron Rivest for RSA Laboratories. Intended as a possible
successor to the Data Encryption Standard, RC5 has a variable word
size, a variable number of rounds, and a variable-length secret key,
so the user can explicitly manipulate the trade-off between higher
speed and higher security. RC5 is suitable for hardware or software
implementations; the encryption and decryption algorithms are
exceptionally simple. A novel feature of RC5 is the heavy use of
data-dependent rotations.
