Code encryption is a vital security measure that transforms source code into an unreadable format, protecting it from unauthorized access and reverse engineering. This process involves converting the code into ciphertext, making it nearly impossible for attackers to understand or manipulate the original logic without the appropriate decryption key.

In mobile app development, code encryption serves as a critical barrier against threats such as malware injection and code theft. By encrypting sensitive algorithms and proprietary technologies, developers ensure that their intellectual property remains confidential. Unlike code obfuscation, which complicates the code structure but does not secure it, encryption provides a robust defense by rendering the code unusable without decryption.
