About Hashing

Cryptographic hash functions take an input (or 'message') and return a fixed-size string of bytes. The output, typically a digest, is unique to each unique input.

MD5: Fast but considered cryptographically broken. Still useful for non-security integrity checks.
SHA-1: Also considered broken for collision resistance, but widely used for git commit IDs.
SHA-256 / SHA-512: Modern, secure standards for most applications.
