MarkEncryption
MarkEncryption encodes and decodes chat messages that carry a configurable prefix, so players sharing a key can read each other's encrypted lines.
What it does
The client-only Fabric mod encrypts outgoing chat messages whose text starts with a chosen prefix, and decrypts incoming messages that use the same prefix and key. Only clients running MarkEncryption with a matching key can read the text. Its author recommends it for anarchy servers. The mod is for Fabric 1.20.4 – 1.21.8, released under the MIT License as open source.
