NAME
       gpgv2 - Verify OpenPGP signatures

SYNOPSIS
       gpgv2 [options] signed_files

DESCRIPTION
       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.

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

OPTIONS
       gpgv2 recognizes	these options:

       --verbose

       -v     Gives more information during processing.	If used	twice, the in-
	      put 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
	      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.

       --ignore-time-conflict
	      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
	      HKCU\Software\GNU\GnuPG:HomeDir.

EXAMPLES
       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.

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".

       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-
       ture and	an index.
