WebHMAC. In cryptography, an HMAC (sometimes expanded as either keyed-hash message authentication code or hash-based message authentication code) is a specific type of message authentication code (MAC) involving a cryptographic hash function and a secret cryptographic key.

The cryptographic strength of the HMAC depends upon the size of the secret key that is used and the security of the underlying hash function used. It has been proven that the security of an HMAC construction is directly related to security properties of the hash function used. The most common attack against HMACs is brute force to uncover the secret key. HMACs are substantially less affected by collisions than their underlying hashing algorithms alone. In particular, Mihir Bell… WebApr 6, 2015 · In TLS, MD5 is used as the compression function for HMAC. The best current security proof for HMAC does not require its compression function to be collision-resistant, so HMAC-MD5 is still considered secure (if distasteful). TLS 1.0 and RC4 are more disconcerting than MD5 in this case.
