Some Key Management Server (KMS) vendors require that you upload your root CA certificate to the KMS. All certificates that are signed by your root CA are then trusted by this KMS.
The root CA certificate that vSphere Virtual Machine Encryption uses is a self-signed certificate that is stored in a separate store in the VMware Endpoint Certificate Store (VECS) on the vCenter Server system.
- Navigate to the vCenter Server.
- Click Configure and select Key Management Servers.
- Select the KMS instance with which you want to establish a trusted connection.
- From the Establish Trust drop-down menu, select Make KMS trust vCenter.
- Select vCenter Root CA Certificate and click Next.
The Download Root CA Certificate dialog box is populated with the root certificate that vCenter Server uses for encryption. This certificate is stored in VECS.
- Copy the certificate to the clipboard or download the certificate as a file.
- Follow the instructions from your KMS vendor to upload the certificate to their system.
Note: Some KMS vendors require that the KMS vendor restarts the KMS to pick up the root certificate that you upload.
