What is Code Obfuscation?

Code obfuscation is a crucial technique in mobile app security that helps protect applications from reverse engineering and tampering. It works by transforming code into an unreadable format while maintaining its functionality, making it difficult for attackers to analyze or modify.

For example, sensitive function names like processPayment() might be renamed to something nonsensical like a1b2c3() to hide their purpose. This added layer of defense is essential in industries that handle sensitive data, such as finance, healthcare, and entertainment, as it helps prevent attacks like repackaging and malware insertion. Developers rely on obfuscation to safeguard intellectual property and ensure the integrity of their apps without sacrificing performance.
