What is a Hash?

A cryptographic hash function takes an input and produces a fixed-size string of characters (the "hash" or "digest"). Hashes are one-way functions -- you cannot reverse them to get the original data. They are used for data integrity verification, password storage, digital signatures, and checksums. This tool uses the Web Crypto API built into your browser, so your data never leaves your device.
