[2/27/24, 11:00 AM EST] CSRC has been experiencing technical issues. If you are unable to access a CSRC page or resource, or get a 503 error, please try reloading the page several times--it may help to wait a few minutes before trying again. We apologize for the inconvenience, and hope to have a solution in place next week.
Algorithm specifications for current FIPS-approved and NIST-recommended block cipher modes are available from the Cryptographic Toolkit.
Current testing includes the following block cipher modes:
For testing of ECB (Electronic Codebook), CBC (Cipher Block Chaining), OFB (Output Feedback),CFB (Cipher Feedback) and CTR (Counter) modes from SP 800-38A, see the CAVP block ciphers page.
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 the block cipher modes listed above.
