Hash Generator
Type or paste any text and this tool instantly generates its SHA-1, SHA-256, SHA-384, and SHA-512 hashes using your browser's built-in Web Crypto API. It runs entirely on your device — free, instant, no sign-up, and nothing is uploaded.
Enter some text to generate its hashes.
Frequently asked questions
Type or paste your text into the box and the tool instantly computes its SHA-1, SHA-256, SHA-384, and SHA-512 hashes. Each result is shown as a hexadecimal string you can copy with one click.
A hash is a fixed-length fingerprint of your input produced by a one-way function: the same input always gives the same hash, but you can't reverse it back to the original. Hashes are used for file-integrity checks, checksums, storing passwords, and digital signatures.
It generates SHA-1, SHA-256, SHA-384, and SHA-512 using the browser's native Web Crypto API. MD5 isn't included because it isn't part of Web Crypto and is considered broken, and SHA-1 is provided for compatibility but is no longer recommended for security-sensitive use.
Yes — hashing happens entirely in your browser with the Web Crypto API, so nothing you type is uploaded or stored anywhere.
