What is the https site certificate

HTTPS protocol is a kind of computer network communication protocol. In recent years, major websites have gradually transferred from the previous HTTP protocol to the website using HTTPS protocol. This is because the HTTP protocol transmits files using plaintext data packets, and now, in the more daily days of network finance and transactions, it is necessary to strengthen the security and confidentiality level of the website, and HTTPS, the enhanced version of HTTP, has made great progress in security. When the user applies for access to the server, the server will send the https site certificate to the user. After the user verifies the validity of the https site certificate, the user generates a password and sends it to the server with public key encryption. The server uses the private key to decrypt it, and finally decrypts it when the two parties communicate.

What technologies are used by browsers and servers to request and link data transmission based on https? According to the above, we can see that asymmetric encryption technology, symmetric encryption technology, hash algorithm and digital certificate are used. So how to make the website HTTPS access? The first thing you need is to apply for a https site certificate. Next, follow the steps to set the certificate password, generate a certificate with a private key, and install it. After installing the https certificate, you can perform subsequent domain name verification operations. You need to click the authorization authentication button and enter the domain name and other information for verification. It should be noted that the domain name needs to be registered. During the process, you will be prompted to save files such as Certificate (* .crt), Private Key (* .key), root certificate ca.pem and sub.class1.server.ca.pem, which need to be uploaded to the server. Next, record the SSL module in the configuration file of the httpd service, and add the virtual host configuration. Finally, define SSLCertificateFile, SSLCertificateKeyFile, SSLCertificateChainFile according to the deployment rules on the server, and complete the basic configuration.

Https site certificate is a necessity for website access using HTTPS protocol, so the choice of https site certificate is particularly important. When choosing and purchasing https site certificates, you must choose large brands with follow-up protection of https certificates. Although the website uses HTTPS protocol, it will inevitably encounter hacker attacks and Trojan virus attacks. In order to ensure the security of the website, choosing a high-quality https certificate brand can be quickly solved when problems arise.
