Hash Generator 🔒 Your data never leaves your browser.
MD5, SHA-1, SHA-256 and SHA-512 of any text — all at once.
⚠ MD5 and SHA-1 are broken for security — use them only for checksums and legacy interop.
About this tool
A hash function maps any input to a fixed-length fingerprint: change one character and the whole hash changes. SHA-256 and SHA-512 are computed with the browser's Web Crypto API; MD5 and SHA-1 are included for checksums and legacy systems — both are cryptographically broken, so never use them for passwords or signatures.
All four hashes update live as you type, entirely on your machine. Handy for verifying file checksums, generating cache keys, or comparing configs without exposing their contents.
