Frequently asked questions
Which hash should I use?
SHA-256 is the modern default for integrity checks and fingerprints. MD5 and SHA-1 are broken for security purposes, so only use them for legacy compatibility or non-security checksums.
Can I hash passwords with this?
These are fast hashes, which are the wrong tool for password storage; use bcrypt, scrypt or Argon2 on a server instead. This tool is for checksums and fingerprints.
Is my text sent anywhere?
No. Hashing happens locally via the Web Crypto API and in-page JavaScript.
