-Subject: [PATCH] crypto/hmac: support EVP_MD_CTX_FLAG_ONESHOT and set it
- properly
-
-Some engines (namely VIA C7 Padlock) work only if EVP_MD_CTX_FLAG_ONESHOT
-is set before final update. This is because some crypto accelerators cannot
-perform non-finalizing transform of the digest.
-
-The usage of EVP_MD_CTX_FLAG_ONESHOT is used semantically slightly
-differently here. It is set before the final EVP_DigestUpdate call, not
-necessarily before EVP_DigestInit call. This will not cause any problems
-though.
