Import Certificates and Keys
​

This page outlines how to protect the Leader to Edge Nodes communications, using an existing TLS/SSL certificate and key.

Cribl Edge expects certificates and keys to be formatted in privacy-enhanced mail (.pem) format. To generate a self-signed certificate and corresponding key, see Securing Cribl Edge.

Import Certificate and Key
​

To use your certificate and key to prepare secure communications between Workers/Edge Nodes and the Leader:

  1. Navigate to the Leader’s Settings > Global > Security > Certificates > New Certificates modal.
  2. Open your TLS/SSL certificate file. (The self-signed certificate example in Configure TLS for API and UI Access used the placeholder name myCert.pem.)
  3. Copy the file’s contents to your clipboard.
  4. Paste the file’s contents into the modal’s Certificate field.

You can skip the preceding three steps: Just drag/drop your .pem file from your filesystem into the Certificate field, or upload it using the button at the field’s upper right.

  1. Open your private key file. (The self-signed certificate example in Configure TLS for API and UI Access used the placeholder name myKey.pem.)
  2. Copy the file’s contents to your clipboard.
  3. Paste the clipboard contents into the same Leader modal’s Private key field.

Here again, you can skip the preceding three steps by dragging/dropping or uploading the .pem file from your filesystem.

  1. Fill in the Name and Description fields.
  2. If you’ve uploaded a self-signed certificate, just Save it now.
  3. If your private key is encrypted, fill in the modal’s Passphrase with the corresponding key. (You can paste the key’s contents, or you can drag/drop or upload the key file.)
  4. If you’re uploading a certificate signed by an external certificate authority - For example, a downloaded Splunk Cloud certificate - import the chain into the CA certificate field before saving the certificate. For details, see Obtain the Certificate Chain (TLS/SSL).
