There is no real standard process for downloading and installing CA certificates. The method adopted depends on many factors, such as the type of server used as the certification authority, the configuration mode of the certification authority, and the operating system used on the device where the CA certificate is installed.
If the Windows server is configured as a certificate authority, in general, the administrator can generate and download certificates through the Web interface. The address of this Web interface is usually https://
If the CA certificate is installed on a Windows PC, it will be installed by the certificate console. On a Windows 8 personal computer, you can access CertLM.msc by running a function locally, thus accessing the certificate store. CA certificates are usually installed in a trusted root certification authority in a third-party root certification authority container.
Generally, if you want to install a CA certificate on a mobile device, you can send the certificate to an email account on the mobile device by email. Open the attachment and the certificate will be installed on the device.
Of course, there are also some special certificates, such as Unicom ca certificate for online tax filing, which need to be manually installed and imported into your tax filing system, but cannot be automatically installed and imported.
