Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] In the embodiment of the present invention, by storing the resource file waiting for the protected file into an image file, and encrypting and protecting the protected file by "packing" the image file, the file can be effectively prevented from being decompiled or stolen .

[0022] In the embodiment of the present invention, the image file may be in a format such as a streaming network graphic format (Portable Network Graphic Format, PNG) or a joint photographic experts group (Joint Photographic Experts Group, JPEG). The file to be protected can be a resource file in a format such as SWF, o...

Abstract

The invention is applied in the field of computer software, and provides a file encryption protection method and a file encryption protection device. The method comprises the following steps of: storing a file to be protected into an image file; and generating the image file stored with the file to be protected. According to the embodiment, by storing the file to be protected such as a resource file or the like into the image file, the file to be protected is not easily compiled or embezzled; and if the image file is not decoded, only a picture is seen, so the purpose of encrypting the file to be protected can be well fulfilled.

Description

technical field [0001] The invention belongs to the field of computers, in particular to a file encryption protection method and device. Background technique [0002] A resource file is typically any non-executable data file used by an application, such as image, audio, and video files. Resource files are widely used in software programs such as software games, and contain strings, pictures, or data in any binary format that can be changed without re-editing the code. [0003] The existing encryption methods for resource files such as SWF files are mainly binary scrambling, code obfuscation, embedding the program as binary file data, and putting resource files on the RealTime Messaging Protocol (RTMP) server, etc., which are easy Be decompiled or misappropriated. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide a file encryption protection method, aiming at solving the problem that existing encrypted resource files ...
