- Analyze a packet trace with thousands of packets containing TLS sessions. Find out which sessions have failures and where. Find out which sessions have performance problems and why. And, we have one hour to do it.
How did we do it?
- We used our SSL Problem Finder product.
- It analyzed the packet trace in 5 minutes. Then, we started looking at the results.
What did we find?
- There were 385 handshakes. 342 were good and 43 handshakes were bad. Some handshakes took over 2 seconds with at least one as bad as 8 seconds.
- Some of the failing handshakes had a bad server certificate.
- There were also some potential application performance problems because of how the application data was sent for encryption. We can tell you of a case where one byte at a time was sent to be encrypted with 20 bytes of overhead per byte (95% overhead!).
- We used the rest of the time to see the proportion of data traffic to the handshake and to analyze the handshake timing.
- We can also see that the Tor browser was used for this session because of the Server Name in the TLS handshake.
