WebCryptographic hash functions play an important role in modern communication technology. The input to a hash function is a file or stream of any size and the output is a fixed-size digital representation of the file that is normally less than 1KB and serves as the fingerprint of the original file (often called the message digest). WebFeb 14, 2024 · Time to read: 4 minutes. Hash-based message authentication code (or HMAC) is a cryptographic authentication technique that uses a hash function and a secret key. With HMAC, you can achieve authentication and verify that data is correct and authentic with shared secrets, as opposed to approaches that use signatures and asymmetric …
