An HMAC is a MAC which is based on a hash function. The basic idea is to concatenate the key and the message, and hash them together. Since it is impossible, given a cryptographic hash, to find out what it is the hash of, knowing the hash (or even a collection of such hashes) does not make it possible to find the key. The key is used in generating the HMAC from a message. 2  The key used for generating HMACS is not anyones public key. 3  Its more like a shared secret between two parties. 4  You could check out the REST API authentication method for AWS stuff to better understand how HMACS are used for URL-signing.
