Our Linux kernel version is 4.14. Monte Carlo Test (MCT) for SHA worked fine using libkcapi. We are trying to perform Monte Carlo Test (MCT) for AES using libkcapi. We not able to get the result successfully. Is it possible to use libkcapi to achieve AES MCT? Regards, Jayalakshmi ^ permalink raw reply [flat|nested] 6+ messages in thread

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].
