-Subject: [PATCH] engines/e_padlock: implement sha1/sha224/sha256 acceleration
-
-Limited support for VIA C7 that works only when EVP_MD_CTX_FLAG_ONESHOT
-is used appropriately (as done by EVP_Digest, and my previous HMAC patch).
-
-Full support for VIA Nano including partial transformation and 64-bit mode.
-
-Benchmarks from VIA Nano 1.6GHz, done with including the previous HMAC and
-apps/speed patches done. From single run, error margin of about 100-200k.
-
-No padlock
