Signed message algorithm

Web6.5.1 Message Digests. A simple hash function takes some input, usually of indefinite length, and produces a small number that is significantly shorter than the input. The function is many to one, in that many (possibly infinite) inputs may generate the same output value.The function is also deterministic in that the same output value is always generated for … WebDec 12, 2024 · A description of the algorithm used to sign the signing string when generating an HTTP Message Signature, or instructions on how to determine that algorithm.
