Hi, Do we have any guidelines documented to decide what should be the algorithm priority. Specially for authenc implementation.Most of the drivers have fixed priority for all algos. Problem comes in when we have cbc(aes), hmac(sha1) and authenc(cbc(aes),hmac(sha1)) implementation in driver. Base authenc driver gets more precedence because of higher priority(enc->base.cra_priority * 10 + auth_base->cra_priority;) What should be the priority of cbc(aes), hmac(sha1) authenc(cbc(aes),hmac(sha1)) Regards Harsh Jain
