Dec 27, 2010help me with handshake logs
Hi,
I'm experienced error while third party was trying to connect to my service using client certificate.
I did tcpdump attached the result.
Can you help me to find the problem.

Hi InfoSec,
The ssldump output shows the server rejected the client's certificate:1 7 1293361272.9715 (0.0011) S>CV3.1(2) Alert level fatal value handshake_failure
If you can get a copy of the client's cert and key, you could test this yourself. The first thing I'd try is to use openssl s_client to check that the client cert is valid for the server cert.

Actually the problem was from the certificate itself signed in wrong way.
This why it was reject by the server.
