IMPLEMENTATION OF TRUELICENSE, AN OPEN-SOURCE CERTIFICATE MANAGEMENT ENGINE

This article addresses the shortcomings of the open-source certificate management engine TrueLicense in terms of security, flexibility, and usability. A new license management system based on RSA asymmetric encryption and hardware binding is proposed, with a focus on strengthening three aspects: preventing time callback attacks through encrypted time anchors, transferring core verification logic to C++to resist JAVA decompilation risks, and implementing code obfuscation to protect software intellectual property. The system significantly improves authorization security through multiple security verification mechanisms, while adopting a non-invasive integrated design to lower the threshold for developers to use. This system can effectively defend against time callback attacks and license forgery, support distributed deployment in high concurrency scenarios, and provide an automated integration solution based on Maven. This article elaborates on the implementation principles, architecture design, and operational processes of the system, providing a reliable solution for enterprise level software authorization management.
