# 1. If no gpg-key is in cache.
|

# a. Run a terminal with a tmux splits (at least a split to enter gpg passphrase).
|
||
# b. Wait until timeout.
|
||
# c. Check every second if a key is now cached.
|
||
# d. Kill dedicated terminal emulator window.
|
||
# 2. (When) a gpg-key is finally cached, simply call the "real" rofi-pass.
