You can make sure decryption works in three ways: - Limit the cipher suites on the client, so that it only advertises non-DH ciphersuites
No chance for that. The client (SUPL agent) is preembedded on millions of terminals already in the market.
- Limit the cipher suites on the server, so that it only chooses non-DH ciphersuites (from the ciphersuites advertised by the client)
Technically I could do that I suppose, but I'm not sure about the implications.
- Make the client or the server log the PreMaster data and point Wireshark to the key log file in the "(Pre-)MasterSecret logfile" SSL protocol preference.
As mentioned earlier the only place where I could practically do it is on the SUPL server. I guess I need to find out from the vendor whether it's possible.
Hope this helps,
Yes, it helped very much. Sometimes you don't see the obvious. Thanks a bunch!
