This article mainly explains "what is the acceleration principle of HTTPS". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "what is the acceleration principle of HTTPS".

What is HTTPS?

Http is called Hypertext transfer Protocol and uses TCP port 80. By default, the data is transmitted in plaintext and can be captured by packet grabbing tools, so on interner, the http servers of some important sites need to use PKI (Public key Infrastructure) technology to encrypt the data! This is HTTPS.

HTTPS is called secure Hypertext transfer Protocol. Using TCP port 443, his data will be encrypted with the public key in PKI, so the packet captured by the packet grabber has no way to see the contents of the package. The security is greatly improved. If you want to decrypt the data, you need to use the private key in PKI. So some websites with high security, such as online banking and e-commerce websites, all need to be visited by HTTPS!

Introduction and advantages of HTTPS acceleration.

HTTPS is a combination of hypertext transfer protocol and SSL/TLS, which is a secure HTTP acceleration. However, the SSL encryption algorithm and password will cause the bottleneck of server CPU resources and degrade the server performance. Using HTTPS acceleration of PLCDN can solve this problem. Through dedicated encryption and decryption equipment, acceleration services are provided on each PLCDN node, and then the content requested by the user is encrypted and then requested to the nearest node. At this time, the node will decrypt the content requested by the user according to the special private key, reduce the authentication pressure on the source server, and finally return it to the end user. HTTPS acceleration not only provides a good access process for users. At the same time, it also ensures the security of the data.

HTTPS acceleration benefits:

Security: the request process is encrypted to ensure the security of data

Convenience: the acceleration process is completely transparent to both the client and the server, and CDN caching rules can be customized

High efficiency: high-quality nodes all over the country, dedicated encryption and decryption acceleration equipment to reduce the pressure of origin server authentication

Stability: self-provided health check function to find that faults can be intelligently directed to healthy and safe nodes

Fast: using SSD solid-state disk storage, the performance of other hard drives is stable and the request speed is faster.

Before using HTTPS acceleration

1. The information service of the website covers a wide range, has a large number of views, and the users are scattered, so the source server of the website can not get the ideal response speed.

2, in the face of traffic emergencies, the website is easy to become the target of hackers, and the security of the website is threatened.

3. For the source servers distributed in the computer room, if some of the servers fail, some users' requests cannot respond normally.

After using HTTPS acceleration

1. Through the network load balancing technology, the user's request is directed to the nearest node, so that the user can access the nearest node.

2. The process of the user's request is encrypted, and then the node will use the private key to decrypt and return it to the user, and the security of the website is guaranteed.

3. The intelligent failover strategy between the node and the server can effectively avoid the failure of the website caused by the failure of the server.

Thank you for your reading, the above is the content of "what is the acceleration principle of HTTPS". After the study of this article, I believe you have a deeper understanding of what the acceleration principle of HTTPS is, and the specific use needs to be verified in practice.
