</noinclude>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. Its first variant was published in 1993, and other variants were published until about 2000. 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 &ndash; '''SAFER+''' and '''SAFER++''' &ndash; were submitted as candidates to the [[AES process]] in 1998 and the [[NESSIE]] project in 2000, respectively. All of the algorithms in the SAFER family are unpatented and available for unrestricted use.
