How do I install a SSL certificate for a website?

The advantage of SSL certificate in the process of network transmission is becoming more and more prominent: encrypting network data transmission, improving the security level of the website, obtaining the trust of the client to the website, and more importantly, protecting the online transaction between the client and the server. SSL certificates for new users who have just come into contact with will find that its encryption is a magical process.

In the past, installing SSL certificates was very complicated, and it was estimated that it would be difficult to complete the installation if you were not a professional technician.

Before deploying the SSL certificate for the website, users can send certificate requests to CA institutions (such as GDCA) according to their own characteristics. At present, GDCA has free SSL certificates with short-term but low security level and single function, and different SSL certificates with high security level and multi-functions. After users have identified the CA organization to cooperate with, they need to provide the correct domain name and email to the CA organization. The CA institution will review the relevant qualifications of the user according to the type of certificate requested by the user.

3. Send CSR to CA organization

When a user issues a certificate request to a CA institution, the CA institution will quickly confirm the user's request and send an email with a CSR link and a private encryption key to the applicant. In the email, CA will ask the user to provide CSR, and the user can automatically copy and paste according to the CSR link generated in the email received.

Next, the user is prompted to create a password to ensure that the user has access to CSR. Users will need this password to renew the certificate, revoke, or make other changes. The CA agency will then send the signing certificate to the applicant by email, and the user must save it on the computer.

4. Install SSL certificate

Many CA organizations will email applicants with step-by-step instructions on how to install the certificate. Click the link provided in the email. Download the certificate, and after the installation is complete, drag the installed files to the domain server space to activate the certificate. Then restart the domain server, force the refresh, and the certificate will be displayed on the website.

In addition, a green padlock is displayed at the beginning of the URL, informing the user that the site has been certified by SSL.
