This article mainly introduces what SSL Certificates algorithm is, the article is very detailed, has a certain reference value, interested friends must read it!

Many small partners who have a little contact with the Internet will definitely know the SSL Certificates, which can open an HTTPS secure channel for the server and client browser of the website. The existence of SSL Certificates protects the information and data security of customers when browsing the web, and also greatly enhances the credibility and security of the website. But I don't know if you have thought about how SSL Certificates can realize this secure encrypted communication function? That is to say, what is the SSL Certificates algorithm?

SSL Certificates In fact, in order to adapt to many different browsers, there are many SSL Certificates algorithms. Here we will briefly introduce two of them.

The first algorithm is AES-GCM, AES-GCM is a very common block encryption algorithm, but this algorithm will produce a disadvantage: that is, the amount of computation will be very large, this disadvantage will lead to performance and power overhead is relatively large. So to solve this problem, Intel introduced an x86 instruction extension called AES NI, which provides hardware support for AES, and for devices that support AES NI instructions, using AES-GCM is undoubtedly the best choice.

The SSL Certificates required by the mobile terminal is also different. For the mobile terminal, ChaCha20-Poly1305 developed by Google is the best choice. This is the second algorithm we want to talk about. ChaCha20-Poly1305 is a new streaming encryption algorithm specially optimized by Google for mobile CPU. Its performance is 3 times higher than that of ordinary algorithms, especially on ARM platforms with reduced instruction set CPU. The effect was more obvious before ARM v8. Therefore, for the mobile SSL SSL Certificates, by using this algorithm, you can greatly reduce the amount of data generated by encryption and decryption, which can improve the user experience, reduce the waiting time, and save battery life.

The above is SSL Certificates algorithm is what all the content, thank you for reading! Hope to share the content to help everyone, more relevant knowledge, welcome to pay attention to the industry information channel!
