Some time ago I needed an automated way to get the certificate DN, signing cert DN, and expiration date from a bunch of SSL web servers. I couldn’t find a free tool out there to do that, so I hacked up this script in python.

You provide it the IP address and it connects, retrieves the aforementioned information, and spits it out. There isn’t any error handling &etc, but I thought someone else might find it helpful. Or use it as a starting point for something more advanced.

It requires the M2Crypto library, since the built-in SSL library for python is SORELY LACKING in functionality.

If you are attending DEFCON this year (or just want to see my slides), the final incarnation of my slides are available here: http://phreakmonkey.com/dc16-ue.zip The slides on the DEFCON CD are out-of-date.

Also, thanks to everyone who came out to the EFF party last night!

My talk is on Saturday at 3:00pm, track 5.

EDIT 2008.08.12:

Another year, another DEFCON gone by.  A quick THANK YOU to everyone who makes DEFCON possible (if you attended that includes you!), and thanks to everyone who attended my talk or walked up to me at some point during the con to share your personal Urban Exploration experiences!  It was a lot of fun.  See you next year!

My company recently de-installed and discarded dozens of these little Nortel Contivity 1010 VPN devices. I pulled one apart and discovered it’s basically a tiny Intel Celeron PC with no keyboard/mouse interface, one serial console port, and two 10/100 Ethernet ports. I decided it would be fun to get Linux to run on one so I could play with it… maybe use it as a small firewall, router, or OpenVPN endpoint.

I built a stripped-down install of Slackware-12.0 with Linux kernel 2.6.21.5. The install includes (amongst other things):

• OpenSSL
• OpenSSH
• OpenVPN
• iptables
• dnsmask
• dhcpcd
