Editor to share with you what the format of the code signature certificate is. I hope you will gain a lot after reading this article. Let's discuss the method together.

In this day and age, we all need to use the Internet, including what you want to eat and what you want to know, you can search and find answers on the Internet, and what you want to watch TV today can also be seen on the Internet in advance. His relationship with many of us is inseparable, so it is necessary to check things, watch news, watch TV, and communicate with them. We must also understand it, such as the format of code signing certificates and code signing certificates and self-signed certificates.

I. Code signing certificate format

Code signature certificate formats are all available in digital, Microsoft, Microsoft Mobile, and brew code signatures, as well as Symbian code, Adobe pdf code, and APP le code. In fact, these codes are different. Make them suitable for the program, some codes are suitable for files, and some are used for encryption, as well as packaged files, and so on. But, uh, the benefits they use are all the same. In order to prevent the code from being tampered with, it will greatly improve the security of the network and protect the rights and interests of developers. The above is the format of the code signature certificate.

II. Code signing Certificate

The code signing certificate starts from applying for a digital certificate. This code is developed by the publisher. Let me take a look at the advantages of using a code signing certificate. If it is used by a developer or that kind of enterprise, if he uses the following verification of the code, he can improve the download of his software, as well as the adoption rate and the distribution rate, the code signature certificate, yes, in the code program, error learning is also unsafe, and can establish a trust relationship between brands, they can improve the system and protect the information of developers. And its existence will also tell users that this software is legal, and since its development, its code has not been tampered with, and the code signing certificate can eliminate unknown publishers popping up in internet and windows systems.

III. Self-signed certificate

Let's talk about how to form a self-signed certificate. Take keytool as an example. We open the explorer and I enter a certificate. At this time, we enter Java in the window of cmd. Of course, some computers may already have GDK installed. If people who do not have gdk installed, they should install gdk first, and then we enter keytool in c MB, and then it will show some parameters, but these parameters need to be translated. When you understand the meaning of the parameters, you have to execute the command. When faced with before, you will find that you can view the details of the certificate file. At this time, you will be prompted to enter the password of the key. After entering the key, you can directly press the enter key to generate the cer file. Double-click this file to see the detailed type of the certificate. Here, I would like to remind you that the certificate below is not trusted by ca institutions. And there are many clients, his default is not to trust this certificate.

After reading this article, I believe you have a certain understanding of the code signing certificate format, want to know more related knowledge, welcome to follow the industry information channel, thank you for reading!
