Does anyone have information on tls session sniffing and can I get the user name and password using in that session.

Thanks...

Keep in mind that is my job to pen test web applications, if it was for malicious use I would not post this! Thank you again!

TLS secures a socket connections well, I doubt you could sniff the password from a TLS session. Your best bet would be to attempt a MITM attack by pretending to be the TLS server. Most users will happily ignore certificate errors :-)

let's say I was arp poisioning or mitm attacking before they got the ssl certificate, theoretically since I got all the certificate information couldn't I use the certificate to decode the ssl traffic?

How would I use these certificates in a sniffer to decode it?

maumercado,
you are right, the only way is to be on one of the two sides of the communications and using a keylogger for example. or using mitm attack, you can use tcpkill or something similar to disconnect the current going session, and when it is established through you  you will be able to see the whole traffice, that is if the client does not authenticate him/her self to the server

Cain and Able can not do it yet.  But I am willing to donate $$ to have it done if anyone is interested.

There is a step by step on how to do this manually in the hakin9 mag last month.  I will ask them if I can post it on here.
