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

In order to prepare for the next major ViaVersion update, you have to do the following things:

Update the dependency by changing

• the group id to com.viaversion,
• the version to 4.0.0,
• the artifact id, depending on your needs, either to viaversion-api or viaversion.

Instead of reimporting or renaming each and every class used, it's easiest to just take a few minutes to do project wide replacements (e.g. Ctrl+Shift+R in IntelliJ).

Replace the base package:
