You can use vSphere Certificate Manager to generate Certificate Signing Requests (CSRs). Submit those CSRs to your enterprise CA or to an external certificate authority for signing. You can use the signed certificates with the different supported certificate replacement processes.

• You can use vSphere Certificate Manager to create the CSR.
• If you prefer to create the CSR manually, the certificate that you send to be signed must meet the following requirements.
  • Key size: 2048 bits or more
  • PEM format. VMware supports PKCS8 and PKCS1 (RSA keys). When keys are added to VECS, they are converted to PKCS8.
  • x509 version 3
  • If you are using custom certificates, the CA extension must be set to true for root certificates, and cert sign must be in the list of requirements.
  • CRL signing must be enabled.
  • Enhanced Key Usage can be either empty or contain Server Authentication.
  • No explicit limit to the length of the certificate chain. VMCA uses the OpenSSL default, which is 10 certificates.
  • Certificates with wildcards or with more than one DNS name are not supported.
  • You cannot create subsidiary CAs of VMCA.

    See the VMware knowledge base article at http://kb.vmware.com/kb/2112009, Creating a Microsoft Certificate Authority Template for SSL certificate creation in vSphere 6.0, for an example using Microsoft Certificate Authority.

vSphere Certificate Manager prompts you for information. The prompts depend on your environment and on the type of certificate that you want to replace.

Log in to your DigiCert account and download the intermediate (DigiCertCA.crt) and your primary certificate (yourdomainname.crt) files. Wps office license key generator. Copy these files, along with the.key file you generated when creating the CSR, to the directory on the server where you keep your certificate and key files.

For any CSR generation, you are prompted for the password of the administrator@vsphere.local user, or for the administrator of the vCenter Single Sign-On domain that you are connecting to.

DigiCert is the world’s premier provider of high—assurance digital certificates—providing trusted SSL, private and managed PKI deployments, and device certificates for the emerging IoT market. Since our founding almost fifteen years ago, we’ve been driven by the idea of finding a better way. DigiCert Certificate Utility for Windows Certificate Management & Troubleshooting Made Easy The free DigiCert Certificate Utility for Windows is an indispensable tool for administrators and a must-have for anyone that uses SSL Certificates for Websites and servers or Code Signing Certificates.

1. Run the vSphere Certificate Manager. OS

   Command
   Windows
   Linux	/usr/lib/vmware-vmca/bin/certificate-manager

2. Select Option 2.
   Initially, you use this option to generate the CSR, not to replace certificates.
3. Supply the password and the Platform Services Controller IP address or host name if prompted.
4. 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.
5. Name the certificate signing request (CSR) root_signing_cert.csr.
6. Send the CSR to your enterprise or external CA for signing and name the resulting signed certificate root_signing_cert.cer.
7. In a text editor, combine the certificates as follows.
8. Save the file as root_signing_chain.cer.
