Dataset Details

The dataset contains a collection of metadata related to the net new X.509 certificates observed in each study when considering all SSL studies that ran prior. The _hosts and _endpoints files provide mapping between the IPs/endpoints and the fingerprint of the X.509 certificate presented. The _certs file provides a mapping of the net new certificates from a given study and the corresponding fingerprint. The _names file provides a mapping of the X.509 certificate name (CN) to its fingerprint.
