Editor to share with you what is the working principle of the private key of ssl certificate. I hope you will gain a lot after reading this article. Let's discuss the methods together.

I believe many netizens know the role of ssl certificate in the Internet, and know that ssl certificate can open a secure channel for the client and server of the website to protect the information of customers in the website. But even many people who have frequent contact with the Internet do not know how ssl certificates work. Why can the ssl certificate protect the information and data when we browse the website? This is due to the two keys generated after the website deploys the ssl certificate, one is called the private key and the other is the public key.

The public key of the ssl certificate is automatically generated when we make the CSR file when applying for the ssl certificate, and the private key of the ssl certificate is a filling option when applying for the ssl certificate. Generally speaking, the private key of the ssl certificate is set by yourself and saved by the website. The certificate request file is submitted to the CA institution for authentication and signature. After the public, the private key of the ssl certificate will match the public key you generated when you created the csr file, so that the public key and private key are the only pair.

After the private key of the ssl certificate is paired with the public key, you can begin to protect the information data of the website. The division of the two keys is clear: first, when customers transfer their own information to the website, they need a public key to open this secure channel for it, and the information can be transmitted in the secure channel. If you want to obtain the information in the secure channel, you need a private key to open the exit of the channel. The joint action of public key and private key protects the information data of the website very well.

Although the private key can protect the information data well, if the security of the private key can not be guaranteed, it means that others can also use this private key to open a secure channel, so the private key set by oneself can also be assigned a protection password, which can protect the ssl certificate private key while protecting the website information data.

After reading this article, I believe you have a certain understanding of how the ssl certificate private key works. You want to know more about it. Welcome to follow the industry information channel. Thank you for your reading!
