.SH NAME
gpg\-key2latex \- Generate a LaTeX file for fingerprint slips.
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.IP "\fBgpg\-key2latex\fR [\fB\-p\fR \fIpapersize\fR] [\fB\-s\fR] [\fB\-\-show\-photo\fR] [\fB\-\-show\-qrcode\fR] \fIkeyid\fR [\fIkeyid\fR...]" 4
.IX Item "gpg-key2latex [-p papersize] [-s] [--show-photo] [--show-qrcode] keyid [keyid...]"
.SH DESCRIPTION
.IX Header "DESCRIPTION"
gpg\-key2latex generates a LaTeX file with an OpenPGP key fingerprint and
User IDs, repeated as often as it fits on a single page.  The LaTeX data
is written to STDOUT.
Note: In most cases the generated file can be compiled to PDF using
\&\fBpdflatex\fR\|(1), but \fBxelatex\fR\|(1) is required if some UID contains CJK
characters.
.SH OPTIONS
.IX Header "OPTIONS"
.IP "\fB\-p\fR \fIpaper-size\fR, \fB\-\-paper\-size=\fR\fIpaper-size\fR" 4
.IX Item "-p paper-size, --paper-size=paper-size"
Select the output paper size. The default is the output of \fBpaperconf\fR\|(1),
or \fIa4\fR if libpaper-utils isn't installed.
.IP "\fB\-s\fR, \fB\-\-show\-subkeys\fR" 4
.IX Item "-s, --show-subkeys"
Show subkey information.
.IP \fB\-\-show\-photo\fR 4
.IX Item "--show-photo"
Show the first valid user attribute, if any.  Note: This writes JPG
files to the current directory.
.IP \fB\-\-show\-qrcode\fR 4
.IX Item "--show-qrcode"
Show a QR code of the string specified by \fB\-\-qrcode\-data\fR.  Note: This
writes PDF files to the current directory.
Requires \fBqrencode\fR\|(1) and \fBepstopdf\fR\|(1).
.IP \fB\-\-qrcode\-data=\fR\fIstring\fR 4
.IX Item "--qrcode-data=string"
The data to encode in a QR code (implies \fB\-\-show\-qrcode\fR).  The string
"%f" is expanded to the OpenPGP key fingerprint (40 hexadecimal digits,
without spaces); "%k" is expanded to the long (16 hexadecimal digits)
key ID; "%%" is replaced by a single "%".
.Sp
The default data to encode, if \fB\-\-qrcode\-data\fR is not specified, is the
string "OPENPGP4FPR:%f".
.IP \fB\-\-attr\-height\fR 4
.IX Item "--attr-height"
The height, in number of lines, of the photo and QR code.  The default
is the number of User ID, with a maximum of 5.
.IP "\fB\-?\fR, \fB\-\-help\fR" 4
.IX Item "-?, --help"
Print a brief help and exit.
.IP \fB\-\-version\fR 4
.IX Item "--version"
Print the version and exit.
.SH ENVIRONMENT
.IX Header "ENVIRONMENT"
.IP \fIHOME\fR 4
.IX Item "HOME"
The default home directory.
.IP \fIGNUPGBIN\fR 4
.IX Item "GNUPGBIN"
The gpg binary.  Default: \f(CW"gpg"\fR.
.IP \fIGNUPGHOME\fR 4
.IX Item "GNUPGHOME"
The default working directory for gpg.  Default: \f(CW\*(C`$HOME/.gnupg\*(C'\fR.
