What is a Hash?

A hash is a one-way function that converts data of any length into a fixed-length value. The same input always produces the same hash value, but it is impossible to recover the original data from the hash.

SHA-1 vs SHA-256

SHA-1: Produces a 160-bit (40 character) hash. Used in legacy systems.
SHA-256: Produces a 256-bit (64 character) hash. More secure and preferred in modern applications.
