About Old Encryption

It seems like it has been broken, but if you still want to use it, here are all the versions prepared so far:

• v1-showroom (download):
  • Old and very basic encryptor with Custom Showroom support;
  • Has been broken for sure.
• v1-noshowroom (download):
  • Old encryptor without showroom support;
  • Faster in-game, but doesn’t protect against Ninja Ripper.
• v3 (download):
  • Introduces Ninja Ripper protection, but it can be circumvented sometimes;
  • Doesn’t work with the oldest CSPs.
• v5 (download):
  • Better protecting against Ninja Ripper;
  • To ensure better mods quality, requires car LODs, doesn’t allow to use non-DDS textures or skip COCKPIT_HR node;
  • Data validation (used for things like server locking) can be circumvented.
• v6 (download):
  • Data validation issue fixed;
  • Because of Simplygon becoming unavailable, no longer requires car LODs.
• v7 (download):
  • CSP 0.2.8 or newer;
  • Now CM can use Polygon Cruncher to generate car LODs, so this one requires LODs again;
  • DDS textures are no longer compressed to better reflect overall mod quality and resource consumption (it’s not like previously there was any real texture protection).

Full documentation is available here. As for LODs requirement, please consider adding LODs to your cars, CM with Polygon Cruncher can generate those for you. They can massively improve in-game performance if you have more than a single car on a track!
