Decrypt application encrypted binaries on macOS when SIP-enabled.
This works well and compiles for iOS nicely, if you want use it at iOS devices, you can use build-ios.sh (Thanks @dlevi309).

Principle
This was discovered independently when analyzing kernel sources, but it appears that the technique was first introduced on iOS :
https://github.com/JohnCoates/flexdecrypt
but now works on macOS:
