How it works
A hash is a fixed-size "fingerprint" generated from any text — useful for verifying file integrity, comparing passwords without storing them in plain text, or generating deterministic identifiers. 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.
