SHA-256 Hash Generator
About this tool
SHA-256 is a cryptographic hash function that turns any text into a fixed 64-character fingerprint. It is used to verify file integrity, store password hashes, and fingerprint data. This tool computes hashes with your browser's built-in WebCrypto API, falling back to a pure-JavaScript implementation when WebCrypto is unavailable (for example, on non-HTTPS pages).
