About the Hash Generator
Generate MD5, SHA-1, and SHA-256 hashes from any text in your browser. SHA-1 and SHA-256 use the native Web Crypto API for speed and accuracy, and MD5 is implemented in pure JavaScript locally — your input never leaves your device.
How to use the Hash Generator
- 1Type or paste your text into the input area.
- 2All three hashes update live as you type.
- 3Click the "Copy" button next to any hash to copy it.
- 4Clear the input and start again any time — nothing is stored.
Why use our Hash Generator
Three algorithms
MD5, SHA-1, and SHA-256 generated side by side from the same input.
Web Crypto powered
SHA-1 and SHA-256 use the browser's native crypto.subtle for correctness.
Live updates
Hashes are recomputed instantly as you edit the text — no submit button.
Private & free
Everything runs in your browser; nothing is logged, uploaded, or shared.
Frequently asked questions
Is MD5 still safe to use?+
MD5 is broken for cryptographic use (collisions are easy to find) and should never protect passwords. It's still fine for non-security uses like checksums, cache keys, and integrity hints.
What's the difference between SHA-1 and SHA-256?+
SHA-1 outputs 160 bits and is considered weak for security-sensitive use. SHA-256 outputs 256 bits and is part of the SHA-2 family — the modern default for cryptographic hashing.
Can I hash a file with this tool?+
This tool hashes text. For file hashing, drop the file into a dedicated file-hash tool — we may add one in the future.
Are my hashes or input stored anywhere?+
No. Hashing happens locally in your browser; your text and the resulting hashes are never sent to a server.
