I am from Stockholm, so chances are that you already have dumps from here, as its the capital.
I'm afraid I am not in software development, except from coding java in school 15 years ago.
I was thinking I would just write a powershell script to parse the data, but first I need to understand how its organised.
I was thinking that since your application is working I could use it to verify my own parser more easily.
I will get to work with the PDFs
It would be nice to finish the application... Are you into software development?
]]>DES-MAC: http://www.freesoft.org/CIE/RFC/1510/83.htm
With the UID, prepended to the data that you want to calculate mac for.
IV - said to be 8 zeros.
KEY:
The question is if the is a card-key generated from a masterkey or one of the 64 masterkeys is used as key for the des-mac algo.
Cant find anything in the documentation.
After the mac is calculated either the 16 msb or 64 msb are just as mac. Apparently the des-mac should generate a 128bit mac but the last 64bits are redundant.
All in all, there is a lot of false-positives if you want to brute-force it.
I wound if it would be better to simulate traffic with a reader instead of trying to bruteforce.

Gui needs rework, but it can read and analyze a dumpfile from a swedish travelling card (mifare classic).
