Problems solved by technology

[0003] In the traditional technology, the encryption method of SWF files is to download an encryption software from the network, and then encrypt a single SWF file. When the number of SWF files to be encrypted is large, the existing technology has the problem of low encryption efficiency, and before encryption It is also necessary to download the application file in advance, occupying the disk space of the client

Embodiment Construction

[0035] figure 1 It is a flow chart of the first embodiment of the batch processing SWF encryption method of the present invention, such as figure 1 As shown, the batch processing SWF breaking encryption method provided by the embodiment of the present invention is executed by the batch processing SWF breaking encryption device on the server side. The device can be implemented in the form of software and / or hardware. The method includes:

[0036] Step S100, obtaining source SWF files uploaded in batches by clients;

[0037] Step S102, sequentially parsing the source SWF file to obtain the file header of the source SWF file;

[0038] Step S104, write a binary stream in the file header by means of a binary stream, the binary stream includes a key code, the source SWF file becomes a first intermediate file in a non-SWF format, and the first intermediate The file and the second intermediate file are combined and loaded into an encrypted SWF file, wherein the second intermediate f...

Abstract

The invention provides a method and device for processing SWF (Shock Wave Flash) separation encryption in batches. The method comprises the following steps: obtaining source SWF files uploaded by a client in batches; sequentially analyzing the source SWF files and obtaining a file header of the source SWF files; loading a binary stream including a key code in the file header in a binary stream manner, converting the source SWF files into a first intermediate file with a non-SWF format, and combining and loading the first intermediate file and a second intermediate file including a key corresponding to the key code into encrypted SWF files; and sending each encrypted SWF file to the client. Through encrypting the plurality of SWF files in batches, the encryption efficiency is greatly improved, and encryption software does not need to be downloaded, so that the disk capacity of the client is saved.

Description

technical field [0001] The invention relates to computer data encryption technology, in particular to a method and device for bulk processing SWF fragmentation encryption. Background technique [0002] SWF file is the file ending with ".SWF". SWF is the abbreviation of "shock wave flash". It is an animation file format that supports vector and dot matrix graphics. It is widely used in web design, animation production and other fields. SWF file Also commonly referred to as Flash files. Since the SWF file is in plain text after it is released, it needs to be encrypted in order to keep the SWF file confidential. [0003] In the traditional technology, the encryption method of SWF files is to download an encryption software from the network, and then encrypt a single SWF file. When the number of SWF files to be encrypted is large, the existing technology has the problem of low encryption efficiency, and before encryption It is also necessary to download the application file in...
