HOTP OATH has promoted the HOTP algorithm for one-time password (OTP) credentials. It uses available building blocks such as Hashed Message Authentication Codekey and Secure Hash Algorithm-1 and ...

An algorithm ... the "hash," "digest" or "digital fingerprint." Hash functions are a fundamental component in digital signatures, password security, random number generation, message ...

This standard specifies hash algorithms that can be used to generate digests of ... This property is useful in the generation and verification of digital signatures and message authentication codes, ...

But cryptographic hashes are not. Used for digital signatures, authentication methods and blockchains, these hash algorithms are more complicated. See hash and cryptographic hash function.

SHA-1 is pretty much the pinnacle of computer security, an algorithm invented ... down to a particular length (see Diagram). Although the bit string – the hash – is meaningless by itself ...
