DESFire Transport Application, DESFire SAM RSA

We have reset a DESFire  Card and re-written the Transport Apps & files.
We know where the money is (in a "functional" file beneath a "logical file" in a physical file)
Wish I could say more but the card and the apps are under Non-Disclosures
Cant even get the docs in searchable form.

That aint no way to run a railroad, but it gives me a skillset I guess

DESFire SAM  AV2 does 2048 bit RSA


 Times to generate RSA keys (seconds) 10 runs:
 12.66   15.44   32.12   9.98    21.18   17.81   12.06   15.71   36.58   33.45
 roughly equivalent to an old 80386?
