Build a Offline Standalone Root CA(Certificate Authority)
Login into server that is running on Windows Server 2012 which is not connected to Network and domain.
We need to Add Active Directory Certificate Services role. Goto Server Manager Tool and Click on Add and features.
On Server roles page, Select Active Directory Certificate Services and Click Next.
And select Certification Authority on role services page and click Next.
Installation completed and we need to configure Certificate service. Click Configure Active Directory Certificate Services on the Destination server.
Select Certification Authority and click Next
Select Standalone CA and Click Next.
Enterprise CA option will be disabled by default since this server is not part of Domain
We have to select Create a new private key,Key Length to 4096, CA name to ROOTCA, Validity period to 5 Years
Offline Standalone Root CA Configuration is completed.
After the installation, it will place below files in the c:\windows\system32\Certsrv\CertEnroll
Trusted Root Certificate : ROOTCA_ROOTCA.crt
Certificate Revocation List : ROOTCA.crl (which contains the list of revoked certificates)
And we need to export these files and import into Subordnate CA. I will be covering this on Next Post.
