Cryptographic hash function applications

WebJan 25, 2024 · A hash function is a versatile one-way cryptographic algorithm that maps an input of any size to a unique output of a fixed length of bits. The resulting output, which is known as a hash digest, hash value, or hash code, is the resulting unique identifier we mentioned earlier. So, why do we call it a one-way function?

Summary of cryptographic algorithms - according to NIST

WebA cryptographic hash function is a hash function which takes an input (or 'message') and returns a fixed-size string of bytes. The string is called the 'hash value', 'message digest', 'digital fingerprint', 'digest' or 'checksum'. The ideal hash function has three main properties: It is extremely easy to calculate a hash for any given data.
