Hashing a File in Elixir

Wed, 10 Apr 2019 15:47:11 +0000

A hash function is a function that converts a variable size sequence of bytes (a string, a file content etc.) to a fixed size sequence of bytes, called digest. This means that hashing a file of any length, the hash function will always return the same unique sequence of bytes for that file. It’s a sort of digital fingerprint, usually represented by an hexadecimal string of length between 32 and 128 characters.
