FAQ
Why no MD5?
The browser's native Web Crypto doesn't support MD5, and MD5 is no longer secure. This tool offers the stronger SHA family.
Can a hash be reversed?
No, hashing is one-way — you can't recover the original text from a hash, which is why it's used for verification.
Is my data uploaded?
No, everything is computed in your browser with native Web Crypto — your text is never uploaded.
