Sniffing TLS Traffic

Do you have a need to capture and/or analyze TLS traffic? The wolfSSL library includes a useful tool that you can leverage. The wolfSSL sniffer can be used to capture TLS packets and even decrypt them when at least one of the keys is known. This can be done with both live and recorded PCAP traces.

This could be useful for several reasons, including:

  • Analyzing Network Problems
  • Detecting network misuse by internal and external users
  • Monitoring network usage and data in motion
  • Debugging client/server communications

The sniffer supports both TLS v1.2 and TLS v1.3. It can be integrated into any application using our sniffer API’s and it even comes with a complete working example!
