[new cmd] hf iclass chk

iclass_check.png

Testing out the new iclass check keys function on official pm3 v3.1 (latest src)
It works well but have a issue.

  • looks for debit / credit keys.

  • Enhancing it to do Elite/HighSecurity - custom keys will not be an issue.

As seen in the image,  the failed to obtain CC message is a issue with the current implementation of iclass demo/uart.  Its not super stable and will loose sync failing to demod.  Resulting in the above message.

Conclusion: Its a useful command but will demod/uart needs to become more stable.  cool

Re: [new cmd] hf iclass chk

well,  this exercis has taught me that current iclass impl is based on repeating same command a lot of times until it works (if lucky)

A fast implementation for check keys is done,  but the unstable nature of iclass imp makes it not optimal.  Many keys gets skip because of failing to select/reselect card.


request
if someone has access to a iClass elite/high mode enabled card WITH custom-key,  and are able to part from it for some weeks contact me.  I need to run some checks for the AA2 (credit key) .   It would be of great help.
