Cryptography
Hash Function
A mathematical function that maps data of arbitrary size to a fixed-size value.
What is a Hash Function?
A hash function takes an input of any length and produces a fixed-length output called a hash value or digest. Cryptographic hash functions have specific security properties that make them suitable for authentication.
