Frequently asked questions

Should I use MD5 or SHA-1 for passwords?

No. They remain available for legacy checksums, not password storage or new signatures.

What is the difference between a hash and HMAC?

A hash is unkeyed; HMAC combines a secret key with a hash function to authenticate a message.

Are inputs uploaded?

No. Calculations run in the browser.
