--debug, -d Turn on some debugging. First - you need to pipe the passphrase using ECHO. One of the (many) things GPG does is giving you the ability to sign arbitrary messages or files. Enigmail is looking for a GUI authentication program. Wrong command line syntax. If you would configure no-allow-loopback-pinentry, requests from gpg to use a loopback pinentry are rejected. As a prerequisite the agent must be configured to allow the loopback pinentry mode (option --allow-loopback-pinentry). Put this in your ~/.gnupg/gpg-agent.conf: allow-emacs-pinentry allow-loopback-pinentry Then tell gpg-agent to load this configuration with gpgconf in a shell: gpgconf --reload gpg … Users don't normally have a reason to call it directly. pinentry-qt is typically used internally by gpg-agent.

Search for “decryption with GPG” online and you’ll come up with many resources for using GPG on the command line to decrypt a file. As said, the gpg command and password prompt works without issues when executing it at a tty directly, i.e., not inside tmux. The broken behavior also stays the same when using pinentry-tty instead of pinentry-curses. $ gpg --debug-level advanced --expert --decrypt data.gpg gpg: enabled debug flags: memstat trust extprog gpg: AES encrypted data gpg: problem with the agent: No pinentry gpg: encrypted with 1 passphrase Mostly useful for the maintainers. --help Print a usage message summarizing the most useful command-line options.

Start the pinentry server in emacs, 1. This only works if the agent was configured with --allow-loopback-pinentry when it was started and, in my version of gpg at least, if --pinentry-mode loopback is provided on the gpg command line, which has the side-effect of preventing user-configured pinentry programs from being attempted at all. Before OpenSSH 6.7 you need to use socat which is a bit more fragile and requires a loop to stay open. OPTIONS--version Print the program version and licensing information. It launches some pinentry program as its UI (it is just a daemon running headless in the background, after all), then sends it a GETPIN command.

If the pinentry dialog comes up in a terminal other than the one where the gpg process originated, it doesn’t work correctly anyway – the dialog is drawn on screen, but the command prompt (or whatever is running) remains active in the background and grabs input.
