How it works
A hash is a fixed-size "fingerprint" generated from any text — useful for verifying file integrity, checking that two texts are identical, or generating deterministic identifiers. Plain hashes like these are not suitable for storing passwords, which need a salt and a deliberately slow algorithm. This tool uses the browser's native Web Crypto API, with no external library. SHA-1 is available only for compatibility with legacy systems — it's an algorithm with known vulnerabilities and shouldn't be used for anything requiring real security (passwords, signatures, certificates). For any new use, prefer SHA-256 or higher.
