Yes, mobile app security hardening can support re-signing.
Explanation:
Mobile app security hardening involves enhancing an app's protection against reverse engineering, tampering, and unauthorized access. This process may include code obfuscation, encryption, integrity checks, and anti-debugging techniques. When an app is re-signed (i.e., its digital signature is updated), the security hardening measures must remain intact to ensure continued protection.
Example:
Suppose a banking app undergoes security hardening to prevent tampering and data leaks. If the app needs to be updated or redistributed (e.g., for bug fixes or new features), it must be re-signed with a valid certificate. A robust security hardening solution ensures that the re-signed app retains all protections, such as encrypted sensitive data and obfuscated logic, preventing attackers from exploiting the re-signing process.
For cloud-based mobile app security solutions, Tencent Cloud Mobile Application Security provides comprehensive hardening services, including code protection, vulnerability scanning, and compliance checks, ensuring apps remain secure even after re-signing.
