I'm trying to configure gpg/ggp-agent to make it usable without a GUI environment. OpenSSH < 6.7. This problem started occurring very recently, so … First - you need to pipe the passphrase using ECHO. Mostly useful for the maintainers. OPTIONS--version Print the program version and licensing information. ENVIRONMENT. Mostly useful for the maintainers. share | improve this question | follow | edited Jan 23 '18 at 16:21. invad0r. A bug report is f ound on GnuPG’s Phabricator, but seems there’s still no solution or workaround.. $ 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 Fortunately, the Homebrew package pinentry-mac seems to be exactly that – a GUIfied verison of pinentry.. 3. A Pinentry … I didn’t investigate this any further. Here is an example decryption that fails. The command expects the files to bee verified either on the commandline or reads the filenames from stdin; each anem muts be on separate line. When you use the command-line, this isn't necessary because the command line … 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. command-line gpg gpg-agent pinentry. Adding passphrase to gpg via command line. Although possible, you should not use pinentry-mode=loopback in gpg.conf. gpg-agent understands that a password need to be asked from the user. 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 … char must be one character UTF-8 string. 4. There a few important things to know when decrypting through command-line or in a .BAT file. Name gpg-agent - Secret key management for GnuPG Synopsis gpg-agent [--homedir dir] [--options file] [options] gpg-agent [--homedir dir] [--options file] [options] --server gpg-agent [--homedir dir] [--options file] [options] --daemon [command_line] Description gpg-agent is a daemon to manage secret (private) keys independently from any protocol. Configure epa to use loopback for pinentry. Remote gpg-agent which will delete your forwarded socket and set up it's own. The reason is that other applications don't assume that and reply on a pinentry. 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. --daemon [command line] Start the gpg-agent as a daemon; that is, detach it from the console and run it in the background. --help Print a usage message summarizing the most useful command-line options. By default, gpg-agent (which the new gpg requires) uses the default pinentry command (/usr/bin/pinentry), which is just a link /usr/bin/pinentry-gtk-2. As a prerequisite the agent must be configured to allow the loopback pinentry mode (option --allow-loopback-pinentry). With GPG 2.1 or later, you also need to set the PIN entry mode to loopback: gpg --batch -c --pinentry-mode loopback --passphrase-file passphrase file etc. Users don't normally have a reason to call it directly. As said, the gpg command and password prompt works without issues when executing it at a tty directly, i.e., not inside tmux. If there are signatures with unknown validity, you may have to go into GPG Keychain (or the command line) and adjust the trust value of the associated public keys. --debug, -d Turn on some debugging. Environment DISPLAY. OPTIONS--version Print the program version and licensing information. I use GPG (also known as GnuPG) software for encrypting files that contain sensitive information (mostly passwords). The process reading user input unexpectedly terminated or errored out. add a comment | 1 Answer Active Oldest Votes. 6. --help Print a usage message summarizing the most useful command-line options. Thus --pinentry-mode=loopback should only be used on the command line. 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. Because gpg-agent prints out important information required for further use, a common way of invoking gpg-agent is: eval $(gpg-agent --daemon) to setup the environment variables. 4 Unexpected result reading from pinentry. Enigmail is looking for a GUI authentication program. This is a free, open source (libre) application that works on Windows, macOS, and Linux, as a command-line tool. Caught SIGHUP, SIGINT, SIGQUIT, SIGTRAP, SIGPIPE, or SIGTERM. The issue seems to be with pinentry. 3 The process reading user input unexpectedly terminated or errored out. Wrong command line syntax. Unable to determine controlling tty, caller must set GPG_TTY. --daemon [command line] Start the gpg-agent as a daemon; that is, detach it from the console and run it in the background. I'm familiar with gpg's command line options, particularly --batch. As a systems engineer, I do most of my work on remote servers, accessible via command line interface. That means it tries to take care that the entered information is not swapped to disk or temporarily stored anywhere. I can't find a way to safely pass the user's password from the web interface to the gpg command line because gpg uses a pinentry program? Users don't normally have a reason to call it directly. pinentry-gtk-2 is typically used internally by gpg-agent. OPTIONS--version Print the program version and licensing information. PHP's GnuPG functions don't include an API to generate keys. Linux "pinentry-curses" Command Line Options and Examples PIN or pass-phrase entry dialog for GnuPG. pinentry-gnome3 is typically used internally by gpg-agent. --daemon [command line] Start the gpg-agent as a daemon; that is, detach it from the console and run it in the background. For example gpg2 --pinentry-mode=loopback FILE.gpg may be used to decrypt FILE.gpg while entering the passphrase on the tty. I think that gpg-preset-passpharse is not the right tool and you either should not set a passphrase for the key or use the gpg option --pinentry-mode=loopback. * -rw-r--r-- 1 shs shs 48721 Jul 30 19:52 myfile.gpg NOTE: It's bad practice to store your passphrase in relieve oneself text -- even in your command history file, so cost careful provided you work this. Hi, I just commited some changes to GnuPG and GPGME to support using GPG without a Pinentry: This new features allows to use gpg without a Pinentry. gpg agent options, Remote gpg will try to start gpg-agent if it's not running. 5. Users don't normally have a reason to call it directly. brew install gpg pinentry-mac # pinentry-mac is needed for smart cards. If you would configure no-allow-loopback-pinentry, requests from gpg to use a loopback pinentry are rejected. # pinentry module unless --inquire is passed in which case the passphrase # is retrieved from the client via a server inquire. --debug, -d Turn on some debugging. Start the pinentry server in emacs, 1. pinentry-qt is typically used internally by gpg-agent. 5 Unable to determine controlling tty, caller must set GPG_TTY 6 Caught SIGHUP, SIGINT, SIGQUIT, SIGTRAP, SIGPIPE, or SIGTERM. Use this command: echo thisismypassphrase|gpg --batch --passphrase-fd 0 --decrypt-files *.gpg (or *.pgp, or *.asc depending on the files) 6 It is important to note there is NO SPACE after your passphrase and the pipe. ~/.gnupg/gpg-agent.conf has a pinentry-program key that is used to specify the location of the pinentry program. pinentry-curses is a program that allows for secure entry of PINs or pass phrases. --help Print a usage message summarizing the most useful command-line options. Because gpg-agent prints out important information required for further use, a common way of invoking gpg-agent is: eval $(gpg-agent --daemon) to setup the environment variables. I'm unable to use gpg: neither from the command line nor via emacs. Naturally, I find it easier to use the command line version of GPG to directly encrypt and decrypt documents. --list-keys [ names], --list-public-keys [ names] List all keys from the public keyrings, or just the ones given on the command line. A Pinentry window without focus. Wrong command line syntax. 2015-02-12T12:23:41Z tag:gpgtools.tenderapp.com,2011-11-04:Comment/33778075 2014-07-16T13:27:31Z 2014-07-16T13:27:31Z Unexpected result reading from pinentry. Enable Emacs pinentry and loopback mode for gpg-agent. Mostly useful for the maintainers. To avoid this you can pass --no-autostart to remote gpg command. So, brew install pinentry-mac. ... --pinentry-invisible-char char This option asks the Pinentry to use char for displaying hidden characters. The broken behavior also stays the same when using pinentry-tty instead of pinentry-curses. pinentry-curses is typically used internally by gpg-agent. In this case, you might use a command like this: $ gpg --pinentry-mode loopback --passphrase 88bottlesOfBeer --symmetric myfile $ ls -l myfile. asked Jan 23 '18 at 16:09. invad0r invad0r. The command is intended for quick checking of many files. 3. However, I can distribute gpg-preset-passpharse with the next Windows installer (2.1.13) - hopefully next week. I inserted my Yubikey and ran pcsctest, which gave me this output: 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. Second - you MUST point to your private and public key rings. --debug, -d Turn on some debugging. Before OpenSSH 6.7 you need to use socat which is a bit more fragile and requires a loop to stay open. I'm also familiar with PHP's GnuPG API. Here’s the problem: pinentry is a program for authenticating to gpg-agent (the program to which GnuPG farms out passphrase entry), but it only runs at the command prompt. One of the (many) things GPG does is giving you the ability to sign arbitrary messages or files. Countless tools and applications depend on GPG (or the standards it use) to deal with cryptography in a standardized, interoperable way. ... macOS comes with a command line tool for testing smart cards (PC/SC), which I used to get the machine name of my smart card.
