3 Select Option 1 to generate the CSR and answer the prompts.
As part of the process, you have to provide a directory. Certificate Manager places the certificate to
be signed (*.csr file) and the corresponding key file (*.key file) in the directory.
4 Name the certificate signing request (CSR) root_signing_cert.csr.
5 Send the CSR to your enterprise or external CA for signing and name the resulting signed certificate
root_signing_cert.cer.
6 In a text editor, combine the certificates as follows.
-----BEGIN CERTIFICATE-----
Signed VMCA root certificate
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
CA intermediate certificates
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
Root certificate of enterprise or external CA
-----END CERTIFICATE-----
7 Save the file as root_signing_chain.cer.
What to do next
Replace the existing root certificate with the chained root certificate. See Replace VMCA Root Certificate
with Custom Signing Certificate and Replace All Certificates.
Replace VMCA Root Certificate with Custom Signing Certificate and Replace
All Certificates
You can use vSphere Certificate Manager to generate a CSR and sent the CSR to an enterprise or third-
party CA for signing. You can then replace the VMCA root certificate with a custom signing certificate and
replace all existing certificates with certificates that are signed by the custom CA.
You run vSphere Certificate Manager on an embedded installation or on an external
Platform Services Controller to replace the VMCA root certificate with a custom signing certificate.
