The transformation is used to make the source code hard to understand for humans while still preserving the original structure of the source code. It is meant for cases where the source code needs to be shared (e.g. for debugging) but no intellectual property—or sensitive naming information—should be shown. | The transformation is used to make the source code hard to understand for humans while still preserving the original structure of the source code.

In its full scope, obfuscation affects all identifiers, including: | |||
* | * function names and their parameters | ||
* global and local variables | * global and local variables | ||
* user-defined types | * user-defined types | ||

* enumerators | * enumerators | ||
* file names | * file names | ||
Beyond that other information are removed (or can be removed in combination with other transformations): | |||
* comments | |||
* formatting | |||
* resolve typedefs | |||
* inline includes | |||
* merge all C files (unity build) | |||
