You can generate cryptographic hashes such as SHA-256 and SHA-512 from any text — useful for checksums, integrity checks, and verifying data has not changed.

Hashes are computed locally in your browser using the built-in Web Crypto API, so your input never leaves your device.

This tool is for generating and checking hashes, not for production password storage — for that, use a purpose-built password hashing library with salting on your server.
