Hash Generator

Hash Generator produces MD5, SHA-1 and SHA-256 hashes for any text you type, calculated entirely in your own browser so nothing you enter is sent anywhere or stored. All three are generated at once, so there is no need to know in advance which algorithm a task calls for.

People reach for this to confirm two pieces of text are genuinely identical, to generate a checksum to compare against one a colleague or a published source has given them, or to see how a hashing algorithm actually behaves on real input rather than just reading about it.

A hash generated here will always match the equivalent command run on any other machine for the same input, since hash algorithms are standardised and produce identical output everywhere they are implemented correctly.
