Digicert Generate Key File With Cert

0 0 The Digicert Certificate Utility is probably one of the best certificate encryption tool out on the net. A lot of people become scared with key-pair encryption but key-pairs/certificates are actually fundamental easy to figure out. You have a secret private key that rests on a system or application, and that system/application gives to. See Example: SSL Certificate - Generate a Key and CSR. Tableau Server uses Apache, which includes OpenSSL. You can use the OpenSSL toolkit to generate a key file and Certificate Signing Request (CSR) which can then be used to obtain a signed SSL certificate. Steps to generate a key and CSR.

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.

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

For any CSR generation, you are prompted for the password of the [email protected] user, or for the administrator of the vCenter Single Sign-On domain that you are connecting to.


  1. Run the vSphere Certificate Manager. OS
  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.
  • If you created the CSR but cannot locate your key file, the easiest thing to do is reissue your certificate. Start by creating a new CSR—making sure to save the private key to a known location this time—and pair the certificate with that new key. Reissuing is always free with DigiCert.
  • Crt and key files represent both parts of a certificate, key being the private key to the certificate and crt being the signed certificate. It's only one of the ways to generate certs, another way would be having both inside a pem file or another in a p12 container.
