# gpg-key2latex(1)

Generate a LaTeX file for fingerprint slips.

## NAME

gpg-key2latex - Generate a LaTeX file for fingerprint slips.

## SYNOPSIS

- **gpg-key2latex** \[**-p** *papersize*\] \[**-s**\] \[**--show-photo**\] \[**--show-qrcode**\] *keyid* \[*keyid*...\]

  ## 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 [**pdflatex**(1)](/pdflatex/1.md), but [**xelatex**(1)](/xelatex/1.md) is required if some UID contains CJK characters.

## OPTIONS

- **-p** *paper-size*, **--paper-size=***paper-size*

  Select the output paper size. The default is the output of [**paperconf**(1)](/paperconf/1.md), or *a4* if libpaper-utils isn't installed.

- **-s**, **--show-subkeys**

  Show subkey information.

- **--show-photo**

  Show the first valid user attribute, if any.  Note: This writes JPG files to the current directory.

- **--show-qrcode**

  Show a QR code of the string specified by **--qrcode-data**.  Note: This writes PDF files to the current directory. Requires [**qrencode**(1)](/qrencode/1.md) and [**epstopdf**(1)](/epstopdf/1.md).

- **--qrcode-data=***string*

  The data to encode in a QR code (implies **--show-qrcode**).  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 "%".

  The default data to encode, if **--qrcode-data** is not specified, is the string "OPENPGP4FPR:%f".

- **--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.

- **-?**, **--help**

  Print a brief help and exit.

- **--version**

  Print the version and exit.

## ENVIRONMENT

- *HOME*

  The default home directory.

- *GNUPGBIN*

  The gpg binary.  Default: `"gpg"`.

- *GNUPGHOME*

  The default working directory for gpg.  Default: `"$HOME/.gnupg"`.
