Abstract

The invention discloses a Java SDK code encryption and decryption method based on dynamic loading and a terminal, and the method comprises the steps: analyzing a class file in a Jar package, and converting a function into a code-free interface function; encrypting and hiding the Jar packet; after the encryption operation is completed, outputting an interface Jar, a decryption engine Jar and the encrypted Jar; putting the encrypted Jar as a resource file into an application source code project, introducing an interface Jar and a decryption engine Jar into the project, and initializing and calling the decryption engine Jar before the encrypted Jar is used; starting an application integrated with the encrypted SDK, and starting a decryption engine Jar during running to obtain a main class loader of the current process; using the decryption engine Jar and enabling the main class loader to load the decrypted code in the Jar into the memory, and enabling the application to normally call thedecrypted code of the SDK, so that the code security of the SDK is effectively protected.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a dynamic loading-based Java SDK code encryption and decryption method and a terminal. Background technique [0002] Java is an object-oriented programming language. It not only absorbs various advantages of C++ language, but also abandons concepts such as multiple inheritance and pointers that are difficult to understand in C++. Therefore, Java language has two characteristics: powerful and easy to use; Java language As a representative of a static object-oriented programming language, it implements object-oriented theory very well, allowing programmers to perform complex programming in an elegant way of thinking; Java has simplicity, object-oriented, distributed, robustness, security, and platform independence Features such as portability, multi-threading, and dynamics. [0003] Jar is a Java (computer programming language) package file format, usually used to ag...
