WebJan 8, 2024 · HMAC-SHA-256 with a static key is actually about as efficient as just SHA-256. Yes, it uses SHA-256 twice, but with a given key a lot of pre-computation can be performed. PBKDF2 relies on the iteration count (a linear work factor) alone for the key strengthening. So we cannot directly use HMAC-SHA-256 as it doesn't strengthen the … WebAlgorithm – The algorithm used to create the hash of the canonical request. For SHA-256, the algorithm is AWS4-HMAC-SHA256.
