Hash Generator
SHA-1, SHA-256 and SHA-512 hashes of any text, computed in your browser.
SHA-1

How this works
Uses your browser's built-in Web Crypto API — the text never leaves your device. A hash is a one-way fingerprint: the same input always produces the same hash, but you can't reverse a hash back into the original text.
Note: MD5 and SHA-1 are no longer considered cryptographically secure for things like password storage — SHA-256 or SHA-512 are the safer modern choices.
