It came to my attention that the mozilla-ca list of known CA certificate fingerprints do not appear to use commas for separating the (hex-represented) bytes of the fingerprint.

This seems to be a problem to be as for example IDS like suricata provide a tls.fingerprint keyword that expects the fingerprint in that format.

Also any resource I was able to find use the same format, see this [1] as an example

I'm wondering what would be the best approach in this case, I see two alternatives:

  1. adjust the list to hex format (for example adding the same entries twice);
  2. create another list with the hex format

Looking forward for your comments
