💖 GPG-KEY2LATEX(1) 💖

okay bestie, welcome to the User Contributed Perl Documentation section of your manual, and today we're talking about gpg-key2latex — yes she's a Perl queen, yes she's serving LaTeX, and yes she will absolutely make you the cutest little fingerprint slips you've ever seen. 🎀

✨ NAME ✨

gpg-key2latex — generate a LaTeX file for fingerprint slips, periodt. 💅

🌸 SYNOPSIS 🌸

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

she takes a keyid, or like, several *keyid*s if you're feeling generous. no cap.

🦋 DESCRIPTION 🦋

so the whole vibe is: gpg-key2latex generates a LaTeX file that has an OpenPGP key fingerprint and User IDs on it, and it repeats that stuff as many times as it can fit on a single page. like, one page, maximum slay.

the LaTeX data goes straight to STDOUT — no files, no drama, just vibes and output streams. ✨

⚠️ heads up bestie: in most cases you can compile the generated file into a PDF with pdflatex(1), but if some UID contains CJK characters then you lowkey need xelatex(1) instead. iykyk, don't fight it. 😭

💅 OPTIONS 💅

  • -p paper-size, --paper-size=paper-size — pick your output paper size. the default is whatever paperconf(1) spits out, or a4 if libpaper-utils isn't installed. so like, if you don't have libpaper-utils, congrats, you get A4 by default. 🫶
  • -s, --show-subkeys — show the subkey info. main character subkeys deserve their moment too. 👑
  • --show-photo — show the first valid user attribute, if there is one.
😭 not me warning you: this writes JPG files to the current directory. your folder, your problem. keep an eye on her.
  • --show-qrcode — show a QR code of the string specified by --qrcode-data.
🫣 another warning: this writes PDF files to the current directory. also it requires qrencode(1) and epstopdf(1), so make sure they're installed or it's giving broken.
  • --qrcode-data=string — the data to encode in a QR code. this implies --show-qrcode, so asking for it is basically asking for the QR code too. 💫

the string expansions, and these are exact bestie, do not freestyle:

  • %f gets expanded to the OpenPGP key fingerprint — that's 40 hexadecimal digits, without spaces
  • %k gets expanded to the long key ID — that's 16 hexadecimal digits
  • %% gets replaced by a single %

and if you don't specify --qrcode-data at all, the default data to encode is the string "OPENPGP4FPR:%f". iconic default behavior. 🌈

  • --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. so it's like, "match the User IDs, but chill out at 5." 🍓
  • -?, --help — print a brief help and dip. 🙈
  • --version — print the version and exit. short, sweet, slay. ⭐

🌈 ENVIRONMENT 🌈

  • HOME — the default home directory. you know her, you love her.
  • GNUPGBIN — the gpg binary. default: "gpg". that's the one. ✨
  • GNUPGHOME — the default working directory for gpg. default: "$HOME/.gnupg". yes, the classic. 💜
