Android system can allow multiple applications signed by the same certificate to run in one process, and the system actually takes them as a single application, at which point we can deploy our application as a module, and the user can upgrade one of the modules independently. 3. Code or data sharing: Android provides a signature-based permission mechanism, so one application can expose its functionality to another application that is signed with the
Brief Introduction when an application sends an OpenAPI call request based on an http post or HTTPGET request, in order to ensure secure communication between the application and the REST server and prevent malicious attacks such as SecretKey theft and data tampering, the REST server uses the parameter signature mechanism. Before calling OpenAPI, an application must calculate an MD5 Signature for all its re
1, what is the signature?If this problem is not in the Android development to ask, if it is placed in an ordinary section, I think we all know the meaning of the signature. It is often that some of life's commonly used terminology in the field of computer science, people began to confuse. What does the computer do, or what the programming language does, not simulate reality as much as possible? So, the
The mobile phone program developed on the Symbian operating system must be digitally signed before it can be successfully installed on the mobile terminal. The digital signature mechanism can effectively prevent the spread of malicious Mobile Phone programs and protect the legitimate rights and interests of software developers and mobile users. So, how do I implement the Symbian digital signature? Currently
I. Overview of ECDSAElliptic Curve Digital Signature Algorithm (ECDSA) is the simulation of digital Signature Algorithm (DSA) using Elliptic curve cryptography (ECC). ECDSA became the ANSI standard in 1999 and became the IEEE and NIST Standard in 2000. It was accepted by ISO in 1998, and some of its other standards are also considered in the ISO. Unlike the common discrete logarithm problem (discrete logari

When do we have access to the Java method signature? When a JNI call is made, there is also a way to look at the method overload. Overloaded methods have different method signatures, but do not distinguish between return values, and the actual method signature is also rubbed into the return value type, and is javap-s to view the method signature, such as Javap-s

I've been working on ActiveX technology recently. I used Delphi 7 to create an ActiveX control application with ActiveForm. This control produces one. OCX file. Now, I need to deploy this control on the server side, the user's IE will download, install and display the control when the user browses the Web page and chooses to install the control.However, after my control must be digitally signed, IE will not download the installation. The problem is how to digitally sign ActiveX controls. The con

When it comes to signatures, everyone is familiar with it. As we all know, signatures are generally required for major files to ensure their authenticity and effectiveness.
