py3rsa-priv2pub(1)

📦 version 4.9, in debian bookworm, debian trixie, ubuntu jammy, ubuntu noble, ubuntu questing, ubuntu resolute, ubuntu stonking

💖 NAME 💖

py3rsa-priv2pub — she reads a private key and spits out the matching public key. That's it, that's the whole job bestie 🫶

✨ SYNOPSIS ✨

py3rsa-priv2pub [OPTION]...

No positional args, no drama. Just options, and as many as you want.

🦋 DESCRIPTION 🦋

okay so picture this: you hand py3rsa-priv2pub a private key, and it hands you back the corresponding public key. Matchmaker behaviour, honestly. 💅

Both the private key and the public key use the format described in PKCS#1 v1.5 — no cap, that's the whole format situation, it's giving very standardised.

🌸 OPTIONS 🌸

  • -h, --help — shows you the help message and then dips (exits). very "let me explain myself" of her 🎀
  • -i INFILENAME, --input=INFILENAME — the input filename. If you don't specify one, she reads from stdin instead. shy but flexible 💜
  • -i OUTFILENAME, --output=OUTFILENAME — the output filename. If you don't specify one, she writes to stdout instead.
🫶 lowkey obsessed with the fact that the page literally spells both of these with -i — I'm reporting it exactly how it's written, bestie, I don't make the rules, I just transcribe them 💀
  • --inform=INFORM — key format of the input. default is PEM 🌈
  • --outform=OUTFORM — key format of the output. default is PEM ⭐
