May 26, 2017Decrypt TLSv2
Is there any option to decrypt TLSV2 traffic, using ssl dump or using key?

Yes you can decrypt the data by specifying the path, Use SSLDUMP command,
ssldump -Aed -nr /var/tmp/yourpacketcapture.cap -k /config/filestore/files_d/Common_d/certificate_key_d/:Common:www.site.com.key_1

Hi,
Possibility to decrypt traffic depends on ciphers used. If RSA key exchange is used it should be possible to decrypt, if DH is used or any other Forward Secrecy or Perfect Forward Secrecy cipher suites then it is not possible.
It is not possible as well to decrypt resumed session. Capture must contain full SSL Handshake.
