This article mainly introduces what the https client certificate is and what it is useful. what is introduced in the article is very detailed and has a certain reference value. Interested friends must read it!

There are several categories of https certificates, one of which is a https certificate that many people don't know much about, and that is the https client certificate. So what exactly is this so-called https client certificate? let's tell you.

What are the types of https certificates?

There are three types of https certificates: EV, OV and DV certificates.

The client certificate refers to the digital certificate used to prove the identity of the client user in the application system for the https of the server, which is generally bound to the Email of the user, so that the client user can prove his real identity when communicating with the server. The authentication of this https client certificate generally needs a process, specifically, the browser and Web Server need to go through a handshake process to complete identity identification and key exchange, so as to establish a secure connection. The specific process is as follows: the user's browser sends its https version number, encryption setting parameters, session-related data and other necessary information to the server.

When checking the https client certificate, if the check fails, it indicates that the SSL connection cannot be established. If it succeeds, go on. The client browser automatically generates pre-master secret for this query and automatically sends it to the client server after the server's public key is encrypted. If the server requires authentication of the customer, the client also signs some other data and sends it to the server together with the https client certificate. The main purpose of this is to keep the amount of computation of symmetric encryption more than an order of magnitude lower than that of asymmetric encryption, and to improve the operation speed and security of the conversation between the two parties.

Thus it can be seen that https client certificate is a kind of secure digital certificate specially used to verify client users, and because it is https, it is called https client certificate, and its security is very high.
