Hash generator
SHA-1, SHA-256, SHA-384 and SHA-512 digests of any text, computed with the browser's own Web Crypto API. MD5 is deliberately absent — it is broken and Web Crypto refuses to implement it.
Runs entirely in your browser — nothing is uploaded or stored.

Hashing is one-way: these digests identify content, they do not encrypt it. For passwords use a slow, salted KDF such as bcrypt, scrypt or Argon2 on your server instead.
