I ran the server test at ssllabs.com and according to the Scoring PDF I was expecting to score 100% in the key exchange category since my server uses an RSA 4096bit/SHA1withRSA key. however I recieved 90% which according to the PDF is for server with less than 4096bits?
at first I thought it was due the other servers in the chain being lower than 4096bit however after noticing a few other servers with 4096bit for the server and 2048bit for the CA score 100% I was confused.
Am I forgetting something?
