Generate cryptographic hashes from text using the Web Crypto API.
This tool generates cryptographic hashes using the browser's built-in Web Crypto API. Supported algorithms include SHA-256, SHA-512, and SHA-1. All hashing is done client-side — your text never leaves your browser.
A cryptographic hash function takes any input and produces a fixed-size output (the hash or digest). The same input always produces the same hash, but even a tiny change in input produces a completely different hash. Hashes are used for password storage, data integrity verification, digital signatures, and more.
