SYMCRYPTRUN(1)                 GNU Privacy Guard                SYMCRYPTRUN(1)

NAME
       symcryptrun - Call a simple symmetric encryption tool
SYNOPSIS
       symcryptrun   --class   class   --program   program  --keyfile  keyfile
       [--decrypt|--encrypt] [inputfile]

DESCRIPTION
       Sometimes simple encryption tools are already in use for  a  long  time
       and there might be a desire to integrate them into the GnuPG framework.
       The protocols and encryption methods might be non-standard or not  even
       properly  documented,  so  that  a full-fledged encryption tool with an
       interface like gpg is not doable.  symcryptrun provides a solution:  It
       operates  by calling the external encryption/decryption module and pro-
       vides a passphrase for a key using the standard pinentry  based  mecha-
       nism through gpg-agent.
       Note,  that  symcryptrun is only available if GnuPG has been configured
       with '--enable-symcryptrun' at build time.

       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.   Cur-
       rently  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:

       -v
       --verbose
              Output additional information while running.

       -q
       --quiet
              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 W32 systems) by means of the  Registry  entry
              HKCU\Software\GNU\GnuPG:HomeDir.


       --log-file file
              Append  all logging output to file.  Default is to write logging
              information to STDERR.

              The possible exit status codes of symcryptrun are:

       0
                      Success.
       1
                      Some error occured.
       2
                      No valid passphrase was provided.
       3
                      The operation was canceled by the user.

       The full documentation for this tool is maintained as a Texinfo manual.
       If  GnuPG and the info program are properly installed at your site, the
       command
         info gnupg
       should give you access to the complete manual including a  menu  struc-
