FAQ

Which SHA algorithm should I choose?

SHA-256 is generally recommended for balanced security and performance; SHA-1 is deprecated for security use; SHA-384/512 suit higher assurance needs.

Are SHA hashes reversible?

No. SHA is a one-way hash: you can compute the digest from input but cannot recover the input from the digest.

Will my data be uploaded?

No, all computations run locally in your browser.
