Hash Generator

Generate SHA-1, SHA-256, SHA-384 and SHA-512 cryptographic hashes from any text using your browser's native Web Crypto API. Nothing ever leaves your device.

Security note. Hashing is one-way but is not encryption, and older algorithms such as MD5 and SHA-1 are considered broken for security purposes. Do not store user passwords with these digests — use a dedicated, salted password-hashing algorithm (bcrypt, scrypt or Argon2) instead.
