Message Encryption
This mod encrypts messages end to end to the recipient
About this Mod
Message Encryption
This mod lets you encrypt messages end-to-end.
Usage
This mod modifies the /msg command to automatically try to send encrypted messages. You can use /nmsg to send using the vanilla message command, or you can use /emsg to only send encrypted messages.
To send encrypted messages the recipient must also have this mod. So to create an encrypted conversation, you need to ask the recipient to also install this mod.
Other Info
This mod does not support /r, which means if a server has that command, it's going to use the server's messaging system, which is not encrypted. Please use /re for encrypted replies, it does the same thing like /r, but encrypted.
You can always check the source and make merge requests to add new features which this mod is going for.
This mod does not support non-premium accounts, and it is not going to.
You can use this mod in modpacks.
