client key login

i don't have the energy to keep this mod updated all the time, but if you want it ported to a specific minecraft version, please contact me and i'll try my best to do that for you :3

this is unstable and potentially broken! so it might break in unexpected ways! if you find a problem, please send me full details of the error so i can fix it

uses public key cryptography to authenticate to servers instead of going via mojang's account service

features include:

• customise your profile extensively with the identity manager (see gallery)
• create new identities (like accounts) in seconds and switch between them even faster
• use custom skins and capes, hosted on any website (for example you can put an image url directly linking to namemc or similar sites)
• continue to use protocol encryption when mojang is offline
• protection from profile stealing: your uuid is derived from your keypair, which means your player data on the server is linked to the secret on your computer, and the only way to access your player data is to have that secret (or be the server admin)
• "identity theft": clone skin and cape textures from an existing mojang account
• you can still join vanilla servers with the mod installed - it will just use your regular account instead of a client-key identity

does not remove any attempts to contact mojang, so you should still be able to join vanilla servers (as long as you're logged in to minecraft), but this also means if you run a server with this mod you'll need to set enforce-secure-profile to false in server.properties, otherwise there will be consequences (either nobody will be able to join, or in-game chat will be disabled). of course, doing that will spam you with alerts about "insecure server" and so on, so you probably want to use no chat reports alongside this mod
