Abstract

The invention provides a file decryption method and apparatus, involving: receiving the information of a request secret key which is transmitted by a client, wherein the secret key is arranged in a Windows service program, and the Windows service program and the client communicate through a named pipe; and transmitting the secret key to the client so as to allow the client to decrypt the file which is encrypted in the client based on the secret key. According to the invention, the method arranges the decrypted secret key to the Windows service program, and the Windows service program and the software which uses the encrypted file are packaged to the client. When the software is started, the Windows service program is initiated. When the software needs to use the encrypted file, the encrypted file is decrypted. The decrypted secret key is acquired from the Windows service program in an Inter-Process Communication, so that the decrypted secret key is secretly hidden, and the encryption effect is enhanced.

Description

technical field [0001] The present invention relates to the field of information security, and more specifically, to a file decryption method and device. Background technique [0002] At present, with the development of information technology, various software emerges as the times require and are widely used in various fields. Information security issues are also becoming increasingly prominent. Ensuring that information resources in information networks are protected from various types of threats, interference and destruction has become a concern of the whole society. [0003] During the process of storing, processing and exchanging information, there are possibilities of leakage or interception, eavesdropping, tampering and forgery, so confidentiality measures need to be taken. For example, during a game live broadcast, the live broadcast software broadcasts the live broadcast by collecting the content of the camera and the content of the computer. When the live broadca...
