Usage Keywi uses the local storage mechanism of the browser to store some information needed to connect to Keepass. This information includes the key used to authenticate and encrypt the communication with Keepass. The information stored in the local storage of the browser is stored unencrypted. Therefore Keywi encrypts this information (database.key, database.id and database.hash) using 256-bit AES key derived from a user-provided password. This password is asked to the user the first time Keywi is used for encrypting the information. Every time you start Firefox it's asked to decrypt the information. Keywi requires Firefox 51 or later.
