Abstract

The invention discloses a file encryption method and device, electronic equipment and a computer readable medium, and relates to the technical field of security services. A specific embodiment of the method comprises the following steps: compressing a static resource file in a to-be-encrypted file, and confusing script files in the compressed static resource file; replacing a character string value in the to-be-encrypted file, and performing encryption deformation on a class file in the to-be-encrypted file after the character string is replaced; encrypting a configuration file in the file to be encrypted; and binding a machine code to the to-be-encrypted file. According to the embodiment, the technical problem that the application package is very easy to decompile can be solved.

Description

technical field [0001] The invention relates to the technical field of security services, in particular to a file encryption method, device, electronic equipment and computer-readable medium. Background technique [0002] At present, common reinforcement protection technologies mainly include the following types: 1) JAVA obfuscator; 2) JAVA encryption protection; 3) ahead of time compilation technology (AOT); 4) JNI protection; 5) dongle hardware protection. However, these technologies still have the problem of being easily decompiled, resulting in insufficient security. [0003] Java is a cross-platform programming language. Its source code (.java file) is compiled into platform-independent bytecode (.class file), and then dynamically linked at runtime. In this way, the compiled class file will contain a symbol table, so that the application package can be easily decompiled. Contents of the invention [0004] In view of this, the embodiments of the present invention pro...
