Simple HWID lock for your Minecraft clients!
Just initialize the Thingy() on FMLInitializationEvent of your client.
Don't forget to add compile 'commons-codec:commons-codec:1.15' to your build.gradle file. If you are using a gradle newer then 3.0 change the compile 'commons-codec:commons-codec:1.15' to implement 'commons-codec:commons-codec:1.15'. - XeonLyfe :)
