Signed chat

This gist intends on clearing up some of the misinformation surrounding signed chat/the reporting feature Mojang has added to Minecraft 1.19.1. Here you can find both technical information as well as a general explanation of how these work.

Profile keys

After joining a server, clients now send a profile key used for verifying a message's authenticity. This key and thus the whole signing process is optional, but by default, servers enforce secure profiles for clients to send chat messages. Whenever the player sends a chat message and has a key associated, the message will be signed using their own private key, which the server then verifies using the public key sent after join. Assuming signature, timestamp, and message contents line up, the message goes through.

On the other end, clients can also require all broadcasted player messages to be signed, disregarding the ones without sender verified signatures.

Message signatures

Message components

This gist shows you how to use message components in discord.py 2.0

This assumes that you know how Object Orientated Programming in Python works, if you don't know what this is then I recommend that you read this guide.

Installing

You'll need to install discord.py from git to use this (if you don't have git then google how to install it for your OS, I can't be bothered to put it in here...), if you already have this then you can skip to the next section. However if you don't please read the below

The Freenode resignation FAQ, or: "what the fuck is going on?"

IMPORTANT NOTE:

It's come to my attention that some people have been spamming issue trackers with a link to this gist. While it's a good idea to inform people of the situation in principle, please do not do this. By all means spread the word in the communities that you are a part of, after verifying that they are not aware yet, but unsolicited spam is not helpful. It will just frustrate people.
