RS3 NXT Patcher

This is a small Java application that patches the RuneScape NXT client. The tool generates RSA keys, patches them in the launcher and client and generates the hash and CRC of the client. It also compresses the client with a LZMA compression and changes the config URI regex and path based on the settings

Setup & Usage

Simply make sure the dependencies from Gradle are present (Currently only lzma-java). After that go to info.techsdev.nxt.Settings and enter your own RSA keys. If you leave fields empty, they will automatically be generated and printed to the console. Leave the launcher keys empty for the first run, those are required for the hash.

Once you configured the patcher, put client.exe (Your non-patched NXT client) and launcher.exe (Your non-patched NXT launcher, which can be found at C:\Program Files\Jagex\RuneScape Launcher) in a folder named 'library', then run info.techsdev.nxt.Patcher

Save the console output when the patcher generates keys for you - you will need them later on. Save the launcher RSA keys to prevent having to release a new launcher every client update.
