Modest mifare classic / ultralight Gui tool

hi guys,

i wrote a small gui to mifare classic / ultralight. It's written using last qt sdk and libnfc.
It has several helpful features
Auto Authentication from key list. Reading, Writing, parsing of sector trailer (taken from micmd tool) . Possibility of adding your own authentication keys (Ascii/Hex). Listening mode. The app will check and automatically read new tag in the field.  Ascii / Hex view.

I just did this app for a project at uni so i didn't develop the others mifare classic commands (Decrement increment etc) i didn't need. It wouldn't be hard to though.
Since my programming skills are awful i'm not able to release the software under the different platforms and it is tested only under windows xp sp3. I guess you need to add qt dlls in the folder!

Simply type connect. The reader will search for tags currently supported Mifare classic 1k 4k mini e ultralight. Then if you want write data simply start typing in the write data cell.. if you want to write a sectore trailer double click the corresponding   write cell. if you want to parse double click sector cell. Remember once authentication loop started you cannot stop it unless you remove your tag. Clear user memory will set all the block in the tag to 0 (sector trailers aren't affected. I hope!:) ) Be careful while using this function. You can authenticate by typing an input form will appear where you can type Hex 12 digits key or 6 Ascii digits key the app will take care of the conversion same holds for the auth key list

I would like to know your opinion about it and if it appear to be useful to the community i will release the code.
(There might be several bugs around!)

Enjoy

Bye!
