Hi Stephen, I to add the backend support using libkcapi APIs to exercise Kernel CAVP. Can you please confirm if my understanding is correct?

I have the ACVP testing implemented completely for AES (ECB, CBC, CFB8, CFB128, CTR, XTS, GCM internal and external IV generation, CCM), TDES (ECB, CTR, CBC), SHA, HMAC, CMAC (AES and TDES). I did not yet try TDES CFB8 and CFB64 through, but it should work out of the box. AES-KW is the only one that cannot be tested through libkcapi as AF_ALG has one shortcoming preventing this test. The testing is implemented with [1] but the libkcapi test backend is not public. The public code in [1] already implements the MCT. So, if you want to use [1], all you need to implement is a libkcapi backend that just invokes the ciphers as defined by the API in [1]. [1] https://github.com/smuellerDD/acvpparser Ciao Stephan
