  1. Go to the following website: https://certmanager.websecurity.symantec.com/mcelp/enroll/index?jur_hash=87f9eb0238518493dc5d5e4c52effc96
    - With Standard SSL in the drop-down list, select Go.
    - Complete the enrollment form, select Apache under Server Platform and then paste the CSR below.
    - Under Certificate Signature Algorithm, be sure to select the 'SHA-256 with RSA' option.
    - Use the challenge phrase '<PASSWORD>' for the Challenge Phrase.
    - Read the Subscriber Agreement and select Accept.
  2. Confirm the purchase by replying to the email you receive from the SSL Administrator.
  3. Usually within 24 hours, the SSL Administrator will email the actual cert.
To apply the cert to a Thor F5 load balancer,
  1. Create a JIRA ticket: https://intake.tool.s.nokia.com/browse/NET
    - Attach the SSL certificate, the CSR, password and <DOMAIN>.pem.key.
To apply the cert to an AWS load balancer,
  1. From the EC2 Management Console, select the LB you wish to secure and select the Listeners tab
    - Select HTTPS for the Load Balancer Protocol and click on Select under SSL Certificate
  2. Fill out the Select Certificate form
    - Certificate Type:       select Upload new
    - Certificate Name:       set to <DOMAIN>
    - Private Key:            <DOMAIN>.rsa.key
    - Public Key Certificate: cert.cer.txt from SSL Administrator from
    - Certificate Chain:      \"Intermediate CA Certificates_RSA-SHA256_Standard_SSL-certchain.pem\"
