  • Hi All,

    Is there a way to decode captured SSL data ?

    I'm troubleshoting SIP and captured traffic is SSL encrypted, I'm capturing on the server and certificate is installed on the same server.

  • We do have an SSL encryption expert on http://www.codeplex.com/nmexperts.  It was designed for HTTP traffic, but you can see how it works with SIP.  It does require that you ahve the private certificate from the server and the entire SSL conversation, including the full negotiation.

    If the expert isn't working for you, please let us know as  it is new and there are some known limitations which we expect to fix soon.

  • If you select the expert form the expert menu and open the help, there's a detailed description of how to use the expert.  But in general you select a specific TCP converstation and run the expert.  You can also look at this blog for additonal info:
