RC2: Overview, Related Topics & Entities

In cryptography, RC2 (also known as ARC2) is a symmetric-key block cipher designed by Ron Rivest in 1987. "RC" stands for "Ron's Code" (see also RC2, RC5 and RC6), but generally called simply RC2. Other ciphers designed by Ron Rivest include RC4, RC5, and RC6.
