Minimalistic password integration in Firefox

Use [Keepass HTTP](https://github.com/pfn/keepasshttp)
No editing of the Keepass database
Using the Firefox web extensions API, to support Electrolysis
Support Keepass, later maybe [Pass](https://www.passwordstore.org/)
Minimal amount of libraries (aes, cryptoheplers and reqwest)
no automatic form filling, i.e. only when the user wants to. This is very important because:
no injecting of buttons or icons into forms

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. First time

When Firefox starts You will be asked to unlock the Secure Storage using the same password as during the setup. Screenshot Fill in credentials

elect the username input field
right click and choose "Fill username and password" inside the "Keywi" submenu. It's possible to only fill your username or password. Screenshot
click "Allow" when keepass asks permission for the request to the credentials

Keyboard shortcuts The following shortcuts are supported:

Ctrl + Shift + F Fill username and password in the current active input field (only the username will be filled when no password field is found)
Ctrl + Shift + D Fill only password in the current active input field

Multiple Credentials for one URL When Keepass finds multiple Credentials for one URL, it will ask you to select one: Screenshot Disable "Remember for logins" in Firefox To provide a better user experience we advise to disable the feature in Firefox to remember logins.
