🎀 NAME 🎀

tang-show-keys — outputs signing key thumbprints, and honestly it's giving “trust but verify” energy 💅

✨ SYNOPSIS ✨

tang-show-keys [<PORT>]

🦋 DESCRIPTION 🦋

okay so sometimes you lowkey need to manually verify that a client actually got the expected Tang advertisement. bestie, it's a whole vibe check for cryptography 🔥

The client will usually show the thumbprints of the signing keys in the advertisement it got, and this tool will show the thumbprints of the signing keys used by the Tang server on localhost. If these two sets of thumbprints agree, the client has the right advertisement and it is safe to let the client use it. no cap, that's the whole point 🫶

<PORT> is the port that the Tang server is listening on on localhost. It defaults to 80. iconic default behavior, honestly ✨

lowkey important: the comparison only means something when those two sets of thumbprints actually agree. don't skip the vibe check 😭
