       gpgv2 - Verify OpenPGP signatures

       gpgv2 [options] signed_files

       gpgv2 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.

       gpgv2 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 environ‐
       ment variable. An option may be used to specify another keyring or even
       multiple keyrings.

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

       gpgv2 recognizes these options:


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


       -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
	      filename	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.

	      GnuPG  normally  checks that the timestamps associated with keys
	      and signatures have plausible values. However, sometimes a  sig‐
	      nature  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
	      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

       gpgv2 pgpfile

       gpgv2 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.

	      The default keyring with the allowed keys.

       HOME   Used to locate the default home directory.

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


       The full documentation for this tool is maintained as a Texinfo manual.

       ture and an index.
