CCTOO од AndAlex

This simple tool can turn your single secret gesture (or a master-password) into a particular password for any website you need. It's possible to make, using additional information you provide (the site name and, optionally, the hash salt) and a cryptographic hash function. Then, it puts the result right in an active input field in your open browser tab. Everything works in a fully autonomous manner on your device - it doesn't keep information neither locally nor sends it anywhere.
