Problems solved by technology

However, in the above solution, the inventor found in the research process that by encrypting the source code and then generating an executable file, the executable file can still be compiled into source code by a decompiler, or the source code will be corrupted. leakage
[0004] At present, no effective solution has been proposed for the technical problems of source code leakage in related technologies

Abstract

The invention relates to a method and device for preventing decompilation of executable files, computer equipment and a medium. The method for preventing decompilation of the executable file comprisesthe steps that a node acquires an encrypted first executable file and file information of the first executable file; the node obtains a secret key used for decrypting the first executable file from the first server according to the file information and the user information of the node; and the node decrypts the first executable file by using the key, and loads the second executable file obtainedby decryption into the memory. Through the method and the device, the technical problem of source code leakage in related technologies is solved, and the safety of the source code is improved.

Description

technical field [0001] The present application relates to the field of computer network security, in particular to a method, device, computer equipment and computer-readable storage medium for preventing decompilation of executable files. Background technique [0002] In the traditional way, such as figure 1 As shown, the source code (Source) is successfully compiled by the compiler (Compiler) and the bytecode (Bytecode) is generated into a package on the hard disk (Disk) (the so-called packaging process), and then the package can be loaded into the computer memory and form a word Bytecode can be loaded into the memory of the JVM by the JVM (java Runtime Environment). During the loading process, it must be processed by the class loader (Calss Loader) before it can be run or executed by the computer. The class loader is the loading word Bytecode tools, it can also be said that the bytecode compiled by the compiler must be recognized by the class loader (Calss Loader), otherw...
