SHA-0 (Secure Hash Algorithm) was a proposal by the U.S. government that was replaced by SHA-1 in FIPS 180-1. SHA-1 addresses the weakness found in SHA-0 by adding an additional circular shift operation. SHA-1 has a reported weakness as far as hash collisions are concerned and awareness should be raised if you are implementing it.
