Abstract

The present invention relates to the technical field of information processing. Disclosed are a file decryption method and device, computer readable storage medium and apparatus. The method comprises: acquiring a first hook function for hooking a file opening function and a second hook function for hooking a file reading function (101); in the process of performing an opening operation on a target file, calling the first hook function to determine whether the target file is in a list of files under decryption, then calling the file opening function to perform the opening operation on the target file, and if the target file is in the list of files under decryption, storing a file handle of the target file to a list of file handles under decryption (102); in the process of performing a reading operation on the target file, calling the second hook function to determine whether the file handle of the target file is in the list of file handles under decryption, if the file handle of the target file is in the list of file handles under decryption, acquiring a decryption key and performing a decryption operation on the target file using the decryption key, and calling the file reading function to perform the reading operation on the target file (103), thereby enabling automatic decryption of a target file at a low level of a system.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a file decryption method, device, computer-readable storage medium and equipment. Background technique [0002] At present, software development usually adopts modular development, that is, the functions of the software are modularized and split, and different modules are responsible for different functions. It can be used independently and enables different developers to develop different modules. However, since different modules are developed by different developers, it is very likely that the file is not decrypted due to someone’s negligence, and thus the read content is wrong. Therefore, there is an urgent need for a method for decrypting files in the prior art . Contents of the invention [0003] In view of the above problems, the present invention is proposed to provide a file decryption method, device, computer-readable storage medium, and equipm...
