This article provides instructions for using OpenSSL to configure an authentication certificate for use with vRealize Operations Tenant App.

Generate a Certificate PEM file for use with vRealize Operations Tenant App

This example is from a Linux machine, but similar steps should work on Windows or Mac machines where OpenSSL is installed.

1. Generate a key pair by running this command:
   
   openssl genrsa -out key_filename.key 2048
    
2. Use the key to generate a certificate signing request by running this command:
   
   openssl req -new -key key_filename.key -out certificate_request.csr
    
3. Submit the CSR file to your Certificate Authority (CA) to obtain a signed certificate.
4. From your Certificate Authority, download the certificate and the complete issuing chain (one or more certificates). Download them in Base64 format.
5. Enter the command to create a single PEM file containing all certificates and the private key. In this step, the example certificate is server_cert.cer and the issuing chain is cacerts.cer.
   
   Note: The order of CA's certs in the .PEM file: Cert, Private Key, Intermediate Cert and then Root Cert.
   
   cat server_cert.cer key_filename.key cacerts.cer > multi_part.pem
   
   Note: In Windows replace cat with type.

The finished PEM file should look similar to the following example, where the number of CERTIFICATE sections depends on the length of the issuing chain:

-----BEGIN CERTIFICATE-----
(Your Primary SSL certificate: your_domain_name.crt)
-----END CERTIFICATE-----
-----BEGIN RSA PRIVATE KEY-----
(Your Private Key: your_domain_name.key)
-----END RSA PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
(Your Intermediate certificate: DigiCertCA.crt)
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
(Your Root certificate: TrustedRoot.crt)
-----END CERTIFICATE-----

Install a PEM in vRealize Operations Tenant App

Configure a certificate for use with vRealize Operations Tenant App.

1. In a Web browser, navigate to the vRealize Operations Tenant App user interface.

2. Log in with the admin username and password.
3. Navigate to Administration > Support > SSL Certificate.
4. Click Browse and locate the certificate .pem file, and click Open to load the file in the Certificate Information text box.

5. Click Upload.
