9.10.1 List of all commands and options

symcryptrun is invoked this way:

symcryptrun --class CLASS --program PROGRAM --keyfile KEYFILE
   [--decrypt | --encrypt] [inputfile]

For encryption, the plain text must be provided on STDIN or as the argument inputfile, and the ciphertext will be output to STDOUT. For decryption vice versa.

CLASS describes the calling conventions of the external tool. Currently it must be given as ‘confucius’. PROGRAM is the full filename of that external tool.

For the class ‘confucius’ the option --keyfile is required; keyfile is the name of a file containing the secret key, which may be protected by a passphrase. For detailed calling conventions, see the source code.

Note, that gpg-agent must be running before starting symcryptrun.

The following additional options may be used:


Output additional information while running.


Try to be as quiet as possible.

--homedir dir

Set the name of the home directory to dir. If this option is not used, the home directory defaults to ~/.gnupg. It is only recognized when given on the command line. It also overrides any home directory stated through the environment variable GNUPGHOME or (on Windows systems) by means of the Registry entry HKCU\Software\GNU\GnuPG:HomeDir.

On Windows systems it is possible to install GnuPG as a portable application. In this case only this command line option is considered, all other ways to set a home directory are ignored.

To install GnuPG as a portable application under Windows, create an empty file named gpgconf.ctl in the same directory as the tool gpgconf.exe. The root of the installation is then that directory; or, if gpgconf.exe has been installed directly below a directory named bin, its parent directory. You also need to make sure that the following directories exist and are writable: ROOT/home for the GnuPG home and ROOT/usr/local/var/cache/gnupg for internal cache files.

--log-file file

Append all logging output to file. Use socket:// to log to socket. Default is to write logging information to STDERR.

The possible exit status codes of symcryptrun are:




Some error occurred.


No valid passphrase was provided.


The operation was canceled by the user.
