Submission + - An Interactive Graph of the CA Ecosystem
An anonymous reader writes: Researchers of the International Computer Science Institute in Berkeley have created an interactive diagram that shows root-CAs, their intermediates, the relationships between them and how many certificates have been signed by them. The graph was generated by passively monitoring the Internet uplinks of a number of (mostly) edu sites for SSL connections and their certificate Information. Among other things the graph shows that one GoDaddy intermediate signed more than 74,000 certificates and that a German CA uses more than 200 sub-CAs for administrative reasons.
