MD5, SHA-1, SHA-256 hash generator

A text's digest across the most common algorithms, computed live.

MD5, SHA-1, SHA-256 hash generator is a free tool that runs entirely in your browser, with no data ever sent to a server. Compute a text's digest in MD5, SHA-1, SHA-256 and SHA-512.

What it's for

Checking that a downloaded file matches the checksum published by its author, or generating a reference digest to compare two versions of a text.

What this tool does not do

This tool computes a one-way digest : it cannot recover the original text from a hash, and should not be used to store passwords in MD5 or SHA-1.

Frequently asked questions

Is MD5 safe for protecting a password?

No. MD5 and SHA-1 are considered broken for cryptographic use and should no longer be used to store passwords. They remain useful for checking that a file hasn't been altered.

Is my data sent to a server?

No : the text you type is processed entirely in your browser, on your device. It is never transmitted to a server.

Do I need to create an account or install anything?

No : the tool works directly on this page, with no sign-up and no install.
