————How it works
A hash function takes any input and produces a fixed-length fingerprint of it — the same input always produces the same hash, and changing even one character produces a completely different one. SHA-1, SHA-256, and SHA-512 are computed using the browser's built-in Web Crypto API, the same cryptographic engine used for secure connections and digital signatures.
MD5 is included for compatibility with legacy systems that still expect it (checksums, older APIs, cache keys) — it is not cryptographically secure and shouldn't be used for passwords, signatures, or anything where collision resistance matters. For that, prefer SHA-256 or SHA-512.
