In [[cryptography]], '''SAFER''' ('''Secure And Fast Encryption Routine''') is the name of a family of [[block cipher]]s designed primarily by [[James Massey]] (one of the designers of [[IDEA (cipher)|IDEA]]) on behalf of Cylink Corporation. The early '''SAFER K''' and '''SAFER SK''' designs share the same [[encryption]] function, but differ in the number of rounds and the [[key schedule]]. More recent versions — '''SAFER+''' and '''SAFER++''' — were submitted as candidates to the [[AES process]] and the [[NESSIE]] project respectively. All of the algorithms in the SAFER family are unpatented and available for unrestricted use.
