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.
What is Hash Generator MD5/SHA?
Computes MD5, SHA-1, SHA-256, SHA-384 and SHA-512 cryptographic hashes of any text. Hashes are used to verify file integrity, store passwords (with salt) and uniquely identify data. Uses the native Web Crypto API — everything runs in the browser, the text never leaves.
How to use
- Paste or type your text in the main field.
- See all hashes computed in real time.
- Use the copy button on any hash line.
- MD5 and SHA-1 are considered insecure — prefer SHA-256+.
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.
