Embodiment 1

[0024] In order to solve the problem of how to detect whether a digital certificate has cracking risk in the prior art, Embodiment 1 of the present application provides a digital certificate cracking risk detection method.

[0025] The execution subject of the digital certificate cracking risk detection method may be the developer of the application program; or, the execution subject of the digital certificate cracking risk detection method may also be the server used to detect the application program or the detection device running on the server. system. Of course, the execution subject of the digital certificate cracking risk detection method provided in the embodiment of the present application may also be a client (or user end) for detecting an application program, and so on.

[0026] To facilitate the description of Embodiment 1 of the present application, the following detailed descriptions all take the application developer as an example to introduce the digital certifi...

Embodiment 2

[0101] In order to solve the problem in the prior art of how to detect whether a digital certificate has a cracking risk, Embodiment 2 of the present application provides a digital certificate cracking risk detection device 20 . The specific structural diagram of the cracking risk detection device 20 of the digital certificate is as follows: figure 2 As shown, it includes: an acquisition unit 21 , an analysis unit 22 , and a determination unit 23 . The following describes the functions of each unit in detail:

[0102] An acquisition unit 21, configured to acquire the target file in the installation package;

[0103] The parsing unit 22 is configured to parse the target file through the encoding rules of the digital certificate, and determine whether the digital signature can be obtained from the target file;

[0104] The determination unit 23 is configured to determine whether the target file is a digital certificate stored in plain text according to the judgment result.

Abstract

This application discloses a digital certificate cracking risk detection method and device. The method includes: obtaining the target file in the installation package; analyzing the target file through the coding rules of the digital certificate to determine whether the target file can be Obtain a digital signature; determine whether the target file is a digital certificate stored in clear text according to the judgment result. This detection method of determining whether the target file is a digital certificate stored in plain text based on whether the digital signature can be obtained from the target file allows application developers to determine whether the digital certificate in the installation package is stored in plain text. It is determined whether the digital certificate has a cracking risk, thereby solving the problem of how to detect whether the digital certificate has a cracking risk existing in the prior art.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a digital certificate cracking risk detection method and device. Background technique [0002] In recent years, with the rapid development of the Android system, users of Android applications (APP, Application) are increasing day by day. At the same time, the security problems faced by developers and users of Android applications are also increasing day by day. [0003] The Android application program is installed on the mobile terminal through an installation package (APK file). During the installation process of the application program, the digital certificate in the application program is obtained after decompressing the APK file. When a user of a mobile terminal sends a service request to the server, in general, a digital certificate is used to encrypt sensitive information such as the user name and login password in the service request, and then transmits it to ...
