Create a certificate signing request from your ExtraHop system

A certificate signing request (CSR) is a block of encoded text that is given to your Certificate Authority (CA) when you apply for an SSL certificate. The CSR is generated on the ExtraHop system where the SSL certificate will be installed and contains information that will be included in the certificate such as the common name (domain name), organization, locality, and country. The CSR also contains the public key that will be included in the certificate. The CSR is created with the private key from the ExtraHop system, making a key pair.

  1. Log in to the Administration settings on the ExtraHop system through https://<extrahop-hostname-or-IP-address>/admin.
  2. In the Network Settings section, click SSL Certificate.
  3. Click Manage certificates and then click Export a Certificate Signing Request (CSR).
  4. In the Subject Alternative Names section, type the DNS name of the ExtraHop system. You can add multiple DNS names and IP addresses to be protected by a single SSL Certificate.
  5. In the Subject section, complete the following fields. Only the Common Name field is required.
    Field Description Examples
    Common Name The fully qualified domain name (FQDN) of the ExtraHop system. The FQDN must match one of the Subject Alternative Names. *.example.com

    discover.example.com

    E-mail Address The email address of the primary contact for your organization. webmaster@example.com
    Organizational Unit The division of your organization handling the certificate. IT Department
    Organization The legal name of your organization. This entry should not be abbreviated and should include suffixes such as Inc, Corp, or LLC. Example, Inc.
    Locality/City The city where your organization is located. Seattle
    State/Province The state or province where your organization is located. This entry should not be abbreviated. Washington
    Country Code The two-letter ISO code for the country where your organization is located. US
  6. Click Export. The CSR file is automatically downloaded to your computer.

Next steps

Send the CSR file to your certificate authority (CA) to have the CSR signed. When you receive the SSL certificate from the CA, return to the SSL Certificate page in the Administration settings and upload the certificate to the ExtraHop system.
Tip:If your organization requires that the CSR contains a new public key, generate a self-signed certificate to create new key pairs before creating the CSR.
