Hash Generator

The Hash Generator is a free online tool that produces MD5, SHA-1, SHA-256 and SHA-512 digests from any text. The SHA family is computed with the browser's native Web Crypto API, so your input is hashed on your own device and never transmitted or stored.

What does a hash generator produce?

A hash generator turns input text into a fixed-length digest that changes when the input changes. This page calculates MD5, SHA-1, SHA-256, and SHA-512 together, which is useful for checksums, integrity comparisons, protocol debugging, and reproducing values expected by another system.

Text is encoded as UTF-8; the SHA algorithms use Web Crypto and MD5 uses a local implementation. A hash is one-way rather than encrypted data, and MD5 and SHA-1 are collision-broken for security uses. Password storage requires a deliberately slow password hash such as bcrypt, not a fast general-purpose digest.
