smart-pass

UPDATE: Due to collisions with the global keyboard shortcuts on Chrome OS, the default shortcut for this extension has been changed to Ctrl+Shift+P (resp. Cmd+Shift+P on Mac). The keyboard shortcut can always be changed under chrome://extensions/shortcuts.

Fill in login forms using an OpenPGP-enabled smart card.

*** NOTE: This extension requires the Google Smart Card Connector extension to be installed and enabled. ***

This extension is meant to be used with a Google Drive™-synced password store generated by zx2c4's ‘pass’ and encrypted using an RSA key stored on a smart card such as a YubiKey, Nitrokey or a Fellowship smart card.

It is compatible with one of the two storage formats supported by Danny van Kooten’s ‘browserpass’ , which this extension is based on. This storage format is also used by the Android app ‘Password Store’ .
For example, encrypted password files for a login form at ‘https://(www.)login.domain.com/secure.html’ can be stored in any Google Drive™ folder called ‘login.domain.com’ and should have file names of the type ‘username.gpg’, where username is replaced by the username used to log in. The content of the files are the GPG-encrypted passwords for the respective username. Both raw and ASCII armored encrypted files are supported.
There can be multiple logins and/or folders per domain and these files can be encrypted using keys on different smart cards. The decryption request will be sent to the smart card with the matching public key.

On first use, the extension will request read-only access to your files on Google Drive, which is needed to find and read encrypted password files. It will also trigger a warning message from the Smart Card Connector extension, since this extension is not contained in its whitelist of smart card middleware applications.

The smart card PIN (or any other user data) is never stored and is only kept in memory for as long as necessary (or requested by the user in case of PIN caching). The extension requests exclusive access to the smart card reader.

In order to synchronize your local password store with Google Drive™, you can use the CLI tool ‘drive’ .

The extension has been tested on Chrome OS and Ubuntu 16.10 with YubiKeys, but should work on any OS supported by the Smart Card Connector extension and with any smart card obeying the OpenPGP Card 2.0 standard. Note that the Smart Card Connector extension can get in the way of gpg-agent if both are enabled at the same time.
