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 frame-
       work.  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 mod-
       ule and provides a passphrase for a key using the standard pinentry based mechanism 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.  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:

       -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 recog-
	      nized 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 HKCUSoftwareGNUGnuPG: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.

NAME

       gpgv - Verify OpenPGP signatures

SYNOPSIS

       gpgv [options] signed_files

DESCRIPTION

       gpgv is an OpenPGP signature verification tool.

       This program is actually a stripped-down version of gpg which is only able to check signatures. It is somewhat smaller than the fully-blown
       gpg and uses a different (and simpler) way to check that the public keys used to make the signature are valid. There are  no  configuration
       files and only a few options are implemented.

       gpgv  assumes that all keys in the keyring are trustworthy.  By default it uses a keyring named `trustedkeys.gpg' which is assumed to be in
       the home directory as defined by GnuPG or set by an option or an environment variable. An option may be used to specify another keyring	or
       even multiple keyrings.

RETURN VALUE

       The program returns 0 if everything is fine, 1 if at least one signature was bad, and other error codes for fatal errors.

OPTIONS

       gpgv recognizes these options:

       --verbose

       -v     Gives more information during processing. If used twice, the input data is listed in detail.

       --quiet

       -q     Try to be as quiet as possible.

       --keyring file
	      Add  file  to the list of keyrings.  If file begins with a tilde and a slash, these are replaced by the HOME directory. If the file-
	      name does not contain a slash, it is assumed to be in the home-directory ("~/.gnupg" if --homedir is not used).

       --status-fd n
	      Write special status strings to the file descriptor n.  See the file DETAILS in the documentation for a listing of them.

       --logger-fd n
	      Write log output to file descriptor n and not to stderr.

       --ignore-time-conflict
	      GnuPG normally checks that the timestamps associated with keys and signatures have plausible values. However, sometimes a  signature
	      seems to be older than the key due to clock problems. This option turns these checks into warnings.

       --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 recog-
	      nized 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 HKCUSoftwareGNUGnuPG:HomeDir.

EXAMPLES

       gpgv pgpfile

       gpgv sigfile [datafile]
	      Verify  the  signature of the file. The second form is used for detached signatures, where sigfile is the detached signature (either
	      ASCII-armored or binary) and datafile contains the signed data; if datafile is "-" the signed data is expected on stdin; if datafile
	      is  not  given  the name of the file holding the signed data is constructed by cutting off the extension (".asc", ".sig" or ".sign")
	      from sigfile.

FILES

       ~/.gnupg/trustedkeys.gpg
	      The default keyring with the allowed keys.

ENVIRONMENT

       HOME   Used to locate the default home directory.

       GNUPGHOME
	      If set directory used instead of "~/.gnupg".
