Use this script as pinentry to store master password for rbw into your keyring
Usage
- run "rbw-pinentry-keyring setup" once to save master password to keyring
- add "rbw-pinentry-keyring" as "pinentry" in rbw config (${XDG_CONFIG_HOME}/rbw/config.json)
- use rbw as normal
Notes
- needs "secret-tool" to access keyring
- setup tested with pinentry-gnome3, but you can run the "secret-tool store"-command manually as well
- master passwords are stored into the keyring as plaintext, so secure your keyring appropriately
- supports multiple profiles, simply set RBW_PROFILE during setup
- can easily be rewritten to use other backends than keyring by setting the "secret_value"-variable
