Substratum Release 780 Brings Android O DP3 Support, Encrypted Assets for Anti-Piracy, and More!

Substratum has been working on a few new features for the theming community, and they are giving themers and users a chance to try out the new goodies. The latest Substratum Release 780 brings new features such as Encrypted Assets and Android O DP3 Support along with a whole host of performance and bug fixes.

Encrypted Assets is the major new addition to this update, focusing on making it much more difficult for pirates to kang themes. Encrypted Assets is a result of the efforts of the Substratum theme working together with the SlimROMs team to put their recent issues with each other behind them. Substratum is also now open to having Slim on the development alliance with the introduction of the new Substratum Theme Template.

With Encrypted Assets, the assets/overlays folder on the device will be completely encrypted using an AES 128-bit algorithm. The encryption is restricted only to the overlays folder as the teams wanted to minimize platform changes for the time being. There is more work to be done on securing it better to achieve its objectives, but so far, they are ready for a release-preview iteration.

The encryption makes it difficult for pirates to simply “kang” or “recompile” themes, acting as a strong dissuasion against the whole piracy ordeal. This would then greatly motivate dedicated themers to put more work, both quantity and quality wise, into their themes. This also stands to benefit bonafide users as they can now look forward to healthier theme choices rather than deal with bland low-effort ‘reworks’ created with the intention of piracy.

As a side note, profile compilation for encrypted themes is not complete yet. Only OverlayUpdater and OverlayFound works right now.

The Substratum Theme Template also sees an update in the form of v10.0.0 release-preview. The theme template was rewritten in Kotlin, meaning that existing themers looking to upgrade to the new template will be needing to target a minimum API level of 24 (Android 7.0 Nougat). Themers will need the latest Android Studio Canary Preview 3 for Kotlin support, and they should be ready for a full rebase of their existing templates. The Substratum Theme Template readme is also ready with all the needed pointers for Kotlin to make it easier for themers to get started.

And finally, the latest Substratum update also brings Android O DP3 support (OMS). This will allow users to start theming for Android O again on the latest Developer Preview.
