The RC algorithms are a set of invented by . The “RC” may stand for either Rivest’s cipher or, more informally, Ron’s code. Despite the similarity in their names, the algorithms are for the most part unrelated. There have been six RC algorithms so far:
- RC1 was never published.
- was a 64-bit developed in 1987.
- RC3 was broken before ever being used.
- is the world’s most widely used .
- is a 32/64/128-bit block cipher developed in 1994.
- , a 128-bit block cipher based heavily on RC5, was an developed in 1997.
