What is code obfuscation?
App code obfuscation is an essential security technique that transforms the executable code of an app into a format that is unreadable to unauthorized users or hackers, while remaining fully functional. This method ensures the core functions of the code are untouched, safeguarding the app’s logic and purpose. As a widespread strategy for safeguarding mobile app code, obfuscation is key to preventing attempts by bad actors to decompile and reverse engineer the source code, and to protect apps from intellectual property theft.
How does code obfuscation work?
The process consists of some simple but reliable techniques and, when used together, can build a strong layer of defense to protect an app’s source code from attackers. The classification of obfuscation techniques depends on the information they target. Some transformations target the lexical structure of the software, while others target the control flow.
Some examples include simply renaming functions, methods, and classes to use less descriptive names. Additional techniques include removing debug information, such as parameter type, source file, and line number, as well as removing Java annotations.
