Secure Hashing

There are four(4) FIPS-approved* algorithms for generating a condensed representation of a message (message digest): SHA-1, SHA-256, SHA-384, and SHA-512,.

SHA-1,

SHA-256,

SHA-384, and

SHA-512

FIPS 180-2, Secure Hash Standard (SHS), August 2002.

On August 26, 2002, NIST announced the approval of FIPS 180-2, Secure Hash Standard, which contains the specifications for the Secure Hash Algorithms (SHA-1, SHA-256, SHA-384, and SHA-256) with several examples.

Testing / Products

Testing requirements and a validation list are available for SHA-1 implementations. Additional testing for SHA-256, SHA-384, SHA-512 will be available in the near future.

Future Plans

None at this time.

* NIST cryptographic standards are specified in Federal Information Processing Standards (FIPS) Publications. The term "FIPS-approved" indicates something (e.g., a cryptographic algorithm) that is either a) specified in a FIPS or b) adopted in a FIPS and specified either in an appendix to the FIPS or in a document referenced by the FIPS.
