What is a hash?
A cryptographic hash is a fixed-length fingerprint of any data. Even a tiny change in input produces a completely different hash — this property is called the avalanche effect.
Algorithm comparison
- SHA-256 — recommended for security, 256-bit output
- SHA-512 — stronger, 512-bit output
- MD5 — fast, but broken for security use; checksums only
- SHA-1 — deprecated for security, still used in Git
