Embodiment 1

[0020] The embodiment of the present invention provides a cross-platform APP data decryption method, such as figure 1 As shown, the method includes the following steps:

[0021] S1: The client obtains the decryption interface of the encrypted data of the executable program and the parameters corresponding to the decryption interface.

[0022] In this embodiment, the methods for obtaining the decryption interface and the parameters corresponding to the decryption interface are as follows: decompile the executable file through IDA, Hopper and other reverse tools to locate the suspicious data interface; dynamically debug the suspicious data interface and print the log To verify, to determine the decryption interface and the parameters corresponding to the decryption interface.

[0023] S2: The client sends the encrypted data, the decryption interface, and the parameters corresponding to the decryption interface to a third-party platform where the executable program can run.

[...

Embodiment 2

[0031] The present invention also provides a cross-platform APP data decryption system, including a client and a third-party platform. A computer program, when the processor executes the computer program, implements the steps in the above method embodiment of Embodiment 1 of the present invention.

Abstract

The invention relates to a cross-platform APP data decryption method and system. The method comprises the steps that S1, a client obtains a decryption interface of encrypted data of an executable program and parameters corresponding to the decryption interface; s2, the client sends the encrypted data, a decryption interface and parameters corresponding to the decryption interface to a third-party platform capable of being operated by the executable program; s3, the third-party platform calls a decryption interface, decrypts the encrypted data by using parameters corresponding to the decryption interface to obtain decrypted data, and returns the decrypted data to the client; and S4, the client receives the decrypted data and stores the decrypted data. The problem that data decryption of different platforms needs to be operated on different platforms is solved, cross-platform data quick decryption is achieved, data decryption is quickly completed in the process that a complex decryption interface does not need to be analyzed and transplanted, the data extraction efficiency is greatly improved, and precious time is saved.

Description

technical field [0001] The invention relates to the field of data decryption, in particular to a cross-platform APP data decryption method and system. Background technique [0002] As the types of Apps become more and more abundant, various Apps gradually enter people's lives. Different Apps adopt different file encryption protection methods, and a mobile phone often installs a variety of different Apps. It poses a great challenge to rapid evidence collection. The current technology can only rely on manual analysis of the App, locate the encryption algorithm and then restore the encryption method of the files in it. Restoring these algorithms faces a large workload, functions have confusion protection, and there are various custom algorithms, etc., which will consume a lot of time. And energy, and the restored algorithm may not be 100% accurate. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a cross-platform APP da...
