I capture a new handhsake yesterday, But it seem I had a lot of broken one before aircrack-ng finaly detect a good one. By looking at the last 4 packet with the eapol filter in wireshark I was able to see that it was a good handshake because the packet 1,2,3,4 were here. I also check that the replay value was the same for the first 2 packet and the same for the last 2 packet and I make sur that the nouce value was the the same for the first and third packet.
I followed this page to make sure everything was good : http://aircrack-ng.org/doku.php?id=wpa_capture&DokuWiki=074d5917c87bb3032d8c42de85f2e8da
After that I selected the 4 good eapol packet and selected one brocast becon frame and put it in a new file like on the pictures.
