Generating a Key and Obtaining and Registering a Certificate from an SCEP Server

When generating a key on the machine, you can request a Simple Certificate Enrollment Protocol (SCEP) server that manages certificates to issue a certificate. The certificate issued by an SCEP server is registered automatically to the machine.
For information about the algorithms of the keys that can be generated with this machine and certificates that can be requested to be issued, see the specifications of the self-generated key and Certificate Signing Request (CSR). Keys and Certificates
This machine only supports Network Device Enrollment Service (NDES) in Windows Server 2008 R2, Server 2012 R2, and Server 2016 for the SCEP server. HTTPS communication is not supported.
To obtain and register a certificate from an SCEP server, configure the settings for communicating with the SCEP server, and then generate a key and request certificate issuance. You can also configure the settings to request certificate issuance at a specified date and time.
