Hi All, Is there any way in OPENSSL so that it can offload HMAC operation directly to engine. As far as I understood from code, OPENSSL generates ipad/opad internally and uses engine only for HASH functions. Please suggest. I need this as the keys that are being used for this operation are blackened by HW Crypto engine and now only HW can use these keys.
