Hash Generator

About the hash generator

A cryptographic hash turns any input into a fixed-length string of hexadecimal characters. The same input always gives the same hash, but the process cannot be reversed to recover the original text.

Hashes are used to verify that a downloaded file has not been altered, to compare two pieces of data without storing them, and as building blocks in signatures and authentication. SHA-256 is the most widely used of the family.

This generator uses the browser's built-in Web Crypto API, so hashing happens on your device and the text never leaves it. Note that hashing is not encryption and is not a substitute for properly salted password storage.
