In cryptography , RC2 is a block cipher designed by Ron Rivest in 1987. RC stands for Ron s Code or Rivest Cipher other ciphers designed by Rivest include RC4 cipher RC4 , RC5 and RC6 . The development of RC2 was sponsored by Lotus Software Lotus , who were seeking a custom cipher that, after evaluation by the NSA , could be exported as part of their Lotus Notes software. The NSA suggested a couple of changes, which Rivest incorporated. After further negotiations, the cipher was approved for export in 1989. Along with RC4, RC2 with a 40 bit encryption 40 bit key size was treated favourably under US Export of cryptography export regulations for cryptography . Initially, the details of the algorithm were kept secret &mdash proprietary to RSA Security &mdash but on 29 January 1996, source code for RC2 was anonymously posted to the Internet on the Usenet forum, sci.crypt . Mentions of CodeView and SoftICE popular debugger debuggers suggest that it had been reverse engineering reverse engineered . A similar disclosure had occurred earlier with RC4. RC2 is a block size cryptography 64 bit block cipher with a variable size key cryptography key . Its 18 rounds are arranged as a source heavy Feistel network , with 16 rounds of one type MIXING punctuated by two rounds of another type MASHING .
