This memo describes a conventional (secret-key) block encryption
algorithm, called RC2, which may be considered as a proposal for a DES
replacement. The input and output block sizes are 64 bits each. The
key size is variable, from one byte up to 128 bytes, although the
current implementation uses eight bytes.  The algorithm is designed to
be easy to implement on 16-bit microprocessors. On an IBM AT, the
encryption runs about twice as fast as DES (assuming that key
expansion has been done).

This memo provides information for the Internet community.  It does
not specify an Internet standard of any kind.  Distribution of this
memo is unlimited.
