WebOct 1, 2024 · HMAC is not an encryption algorithm. It uses a hash algorithm like SHA256 to create a Message Authentication Code (a MAC) that can be used to verify the integrity of the message, and because it's based on a shared secret key, verify the identity of the sender. There's no encryption in there at all WebAlgorithm – The algorithm used to create the hash of the canonical request. For SHA-256, the algorithm is AWS4-HMAC-SHA256. RequestDateTime – The date and time used in the credential scope.. CredentialScope – The credential scope. This restricts the resulting signature to the specified Region and service.
