The Cryptographic Algorithm Validation Program (CAVP) provides validation testing of FIPS-approved and NIST-recommended cryptographic algorithms and their individual components. Cryptographic algorithm validation is a prerequisite of cryptographic module validation.
Vendors may use any of the NVLAP-accredited Cryptographic and Security Testing (CST) Laboratories to test algorithm implementations.
An algorithm implementation successfully tested by a lab and validated by NIST is added to an appropriate validation list, which identifies the vendor, implementation, operational environment, validation date and algorithm details.
Currently, CAVP tests the following cryptographic algorithms. Follow the links to algorithm specifications, validation testing requirements, validation lists and test vectors.
|Block Ciphers:||AES, Triple DES, Skipjack (decryption only)
Tests for ECB, CBC, CFB and OFB modes.
|Block Cipher Modes:||CCM, CMAC, GCM / GMAC / XPN, Key Wrap, XTS|
|Digital Signatures:||FIPS 186-4: DSA, ECDSA, RSA
FIPS 186-2: DSA, ECDSA, RSA
|Key Derivation Functions||KBKDF|
|Message Authentication:||HMAC (FIPS 198-1)|
|Random Number Generation:||DRBG|

The CAVP Management Manual provides effective guidance for the CAVP Validation Authorities, CST laboratories, and vendors who participate in the program. It outlines the management activities and specific responsibilities of the various participating groups; however, it does not include any cryptographic standards. The manual may also interest consumers who acquire validated cryptographic modules and validated cryptographic algorithm implementations.

The FAQ is primarily intended for use by the testing labs. Vendors may also find the information useful when submitting their algorithms for testing.
The CAVP was established in July 1995 by NIST and the Government of Canada's Communications Security Establishment (CSE). CSD's Security Testing, Validation, and Measurement Group (STVMG) manages the validation testing of cryptographic modules and their underlying cryptographic algorithms through the CAVP and CMVP.
