UPBGE BinaryCrypt

UPBGE BinaryCrypt is a dual-tool system for encrypting and decrypting .blend files allowing a secure deployment of UPBGE games. This system complies with the GPL license of UPBGE/Blender and, at the same time, avoids exposing the encryption password, thus providing a way to protect .blend files in games, should the game developer choose to do so.

It includes the option to generate a password at compile time, which is very useful for offline games, or alternatively, the ability to retrieve the password from an online source.

• upbge_binarycrypt_tool/: Raylib-based GUI to encrypt game data
• upbge_binarycrypt_launcher/: headless binary to decrypt and launch the game

⚠️ WARNING: These are the expected features but are not yet implemented. Once the project reaches a sufficient level of maturity for its intended purpose, I will remove this warning and publish the first release.
