Hash Generator
Generate SHA-1, SHA-256, SHA-384, and SHA-512 hashes. Runs in your browser — no data leaves your device.
Which algorithm should I use?
SHA-256 is the standard for most use cases — file integrity checks, API signatures, certificate fingerprints. SHA-512 offers a larger output and is preferred when extra collision resistance is needed. SHA-1 is considered weak and should only be used for legacy compatibility.
