GitHub Gist: instantly share code, notes, and snippets. Mac OS X: how to generate md5 sha1 sha256 checksums from command line . Use the string retrieved by this property to set the message authentication code (MAC) algorithm name when you call the OpenAlgorithm method. Generating HMACs (Keyed-Hash Message Authentication Code) are often used as a way of proving data integrity and authenticity. HMAC is demonstrably resistant (to 128-bit level) even if an adversary can obtain the MAC of chosen messages, under weak hypothesis for SHA-256 (see M. Bellare: New Proofs for NMAC and HMAC: … Then the final Authenticate-then-Encrypt mode you outline is indeed more commonly referred to as MAC-then-Encrypt or MAC-Encode-Encrypt.
