🌈 NDN...UMP(1) 🌈

okay bestie, this is the NDN...UMP(1) page from ndn-cxx: the NDN C++ library with eXperimental eXtensions 💅✨ We're talking about ndnsec-cert-dump, and it's lowkey iconic.

✨ NAME ✨

ndnsec-cert-dump — export an NDN certificate 💖

🦋 SYNOPSIS 🦋

ndnsec cert-dump [-h] [-p] [-r [-H host] [-P port]] [-i|-k|-f] name
btw, the synopsis also has -h, -r, -H host, and -P port. The OPTIONS section below only gives its own little writeups to the four flags after it, so I'm not inventing extra lore, iykyk. 🫶

🌸 DESCRIPTION 🌸

This command reads an NDN certificate — either from the Public Information Base (PIB) or from the specified file — and prints it on the standard output. It can print it either in Base64 encoding or in a human-readable format. No cap. 💖

By default, name is interpreted as a certificate name. That's the default vibe, periodt. ✨

💅 OPTIONS 💅

  • -i, --identity — interpret name as an identity name. If you use this, the certificate to dump is the default certificate of the identity. 💖
  • -k, --key — interpret name as a key name. If you use this, the certificate to dump is the default certificate of the key. 🔑
  • -f, --file — interpret name as a path to a file containing the certificate. If name is "-", the certificate will be read from the standard input. 🎀
  • -p, --pretty — print the certificate in a human-readable format. It's giving readable, bestie. ✨

🔥 EXAMPLES 🔥

Okay so example one: export a certificate from the local PIB to the standard output with Base64 encoding, and it goes like this:

$ ndnsec cert-dump /ndn/test/david/KEY/%7FE%1C%18%D2%03%BD%3F/self/v=1719080300644

And here's printing the NDN testbed root certificate in human-readable format — the -fp - combo is doing its thing:
