Hi
I try to decode ssl flow with wireshark but I have no decryption occurs.
So I try the sample supplied on SSL Wireshark page(SampleCaptures/snakeoil2_070531.tgz).
I have downloaded the rsasnakeoil2.key into the /tmp directory
and set the SSL preferences RSA Keys list to 127.0.0.1,443,HTTP,/tmp/rsasnakeoil2.key and SSL debug file to /tmp/wiresharkSSL.txt

I have the same result, flow is not decrypted.
In trace file, I have no info on the private key load :


ssl_init keys string:
127.0.0.1,443,http,/tmp/snakeoil2.key
ssl_init found host entry 127.0.0.1,443,http,/tmp/snakeoil2.key
ssl_init addr '127.0.0.1' port '443' filename '/tmp/snakeoil2.key' password(only for p12 file) '(null)'
association_find: TCP port 993 found 0x1102ae0

packet_from_server: is from server - FALSE
dissect_ssl server 127.0.0.1:443
dissect_ssl can't find private key for this server! Try it again with universal port 0 dissect_ssl can't find private key for this server (universal port)! Try it again with universal address 0.0.0.0
dissect_ssl can't find any private key!
 conversation = 0x2b9f11b34880, ssl_session = 0x2b9f11b34b58

Can you help me ?

Thank you very much
