Hash Generator MD5 / SHA

Calculate MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes from any text. Useful for file checksums, signatures and quick integrity checks.

🔒 100% local generation. SHA-1/256/384/512 use the browser's native Web Crypto API. MD5 uses a JS implementation.

Frequently asked questions

Should I use MD5 for passwords or signatures?

No. MD5 is broken for security — use SHA-256 or higher. MD5 is fine for non-security use cases like file checksums.

What is the difference between SHA-256 and SHA-512?

Both are secure. SHA-512 produces a longer 512-bit digest and is slightly slower. SHA-256 is the most common modern default.

Is the text sent anywhere?

No. Hashes are calculated entirely in your browser via the native Web Crypto API.
