Input
Output
Output appears here as you type.
What this does
Uses the browser’s built-in Web Crypto implementation, the same primitive your runtime uses.
Limits
- MD5 is not offered. Web Crypto deliberately omits it because it is broken for anything security-related.
- SHA-1 is included for checking legacy checksums only. Do not use it for security.
Is this private?
Yes, and you can check rather than take our word for it. Open your browser's network tab and run the tool: your file never appears in it, because there is no server to send it to. The whole site is static files.
