CAVP Testing: Secure Hashing

Algorithm Specifications

Algorithm specifications for current FIPS-approved and NIST-recommended secure hashing algorithms are available from the Cryptographic Toolkit.

Current testing includes the following algorithms:

• SHA-1 and SHA-2 Hash functions: SHA-1 SHA-224 SHA-256 SHA-384 SHA-512 SHA-512/224 SHA-512/256 (in FIPS 180-4)
• SHA-3 Hash functions: SHA3-224 SHA3-256 SHA3-384 SHA3-512 and XOFs: SHAKE128 SHAKE256 (in FIPS 202)

Algorithm Validation Testing Requirements

FIPS 202, "SHA-3 Standard: Permutation-Based Hash and Extendable-Output Functions"

Secure Hash Algorithm-3 Validation System (SHA3VS) specifies validation testing requirements for the SHA3 family of functions in FIPS 202.

Testing Notes

• No prerequisites required. (See CAVP Frequently Asked Questions (CAVP FAQ) General Question GEN.5.)

Secure Hash Algorithm

Secure Hash Standard Validation System (SHAVS) specifies validation testing requirements for the SHA-1 and SHA-2 family of functions in FIPS 180-4.

Testing Notes

• No prerequisites required. (See CAVP Frequently Asked Questions (CAVP FAQ) General Question GEN.5.)

Test Vectors

Use of these test vectors does not replace validation obtained through the CAVP.

The test vectors linked below can be used to informally verify the correctness of secure hash algorithm implementations (in FIPS 180-4 and FIPS 202) using the validation systems listed above.

Response files (.rsp): the test vectors are properly formatted in response (.rsp) files. Vendor response files must match this format exactly.

Intermediate results files (.txt): files with intermediate results (.txt) are supplied to help with debugging.

See the README file in each zip file for details.
