Wireshark · Wireshark-users: Re: [Wireshark-users] need help to decrypt SSL packets

["Sake Blok" <sake@xxxxxxxxxx>]

Seems you are doing the right thing.

 

Are you able to decrypt ssl traffic in other tracefiles  with other keys? Or was this your first try?

 

Could you share the output of:

 

ls -l /tmp/esd.key

ls -l `which wireshark`

ls -l `which openssl`

 

.. to see whether it could be a permission problem?

 

And are you able to share the tracefile and key or are they from a production environment?

 

Cheers,

Subject: [Wireshark-users] need help to decrypt SSL packets

I’m running Wireshark 1.1.3 comes with Fedora 11. When I tried to decode the captured FTPS traffics, I’m running into trouble to load the private key into Wireshark. I got the following error message when I started Wireshark:

ssl_init keys string:

10.x.100.25,990,ftps,/tmp/esd.key

ssl_init found host entry 10.x.100.25,990,ftps,/tmp/esd.key

ssl_init addr '10.x.100.25' port '990' filename '/tmp/esd.key' password(only fo

r p12 file) '(null)'

ssl_load_key: can't import pem data

As far as I can tell, the private key looks OK.

[awang@mars tmp]$ more esd.key

What did I miss?
