emmtrix Studio implements | emmtrix Studio implements a combined '''Obfuscation and Anonymization''' transformation that can be enabled via <code>#pragma</code> directives or through the graphical user interface. The transformation renames identifiers so that they become obscure or semantically neutral. | ||
* '''Obfuscation mode''': focuses on concealment while maintaining link compatibility — '''global non-static variables and functions remain unchanged''', ensuring that external linkage and build scripts continue to work out of the box. Local symbols, static function names, parameter names, user‑defined types and other internal identifiers are renamed to hashed values. | |||
* '''Anonymization mode''': performs a superset of obfuscation. '''All possible identifiers are renamed''', stripping even more semantic information than is present in the resulting object code. This mode offers more confidentiality especially for code with many global variables and sensitive function names. | |||
In both modes, the functionality and original structure of the code are preserved. Secure Hash Algorithms '''SHA‑1''' and '''SHA‑256''' are employed as the basis for deterministic renaming. | |||

Even though the transformation is selectable only for functions, it can affect other identifiers, as well, depending on the user settings.
