[Muscle] Some issues with Aladdin eToken PRO 72K (Athena OS755)

[Joao Pedro]

Hi all,

The Aladdin eToken PRO 72K is based on the Athena OS755 Java Card OS  
(more information here: http://www.athena-scs.com/product.asp?pid=32).

I've downloaded the MCardApplet, library and tools from the SVN  
repository. I've been able to compile all components and have  
successfully loaded the applet on the card and initialize it.

All is working fine, except two things:

1. The card generates a 2048 bit RSA keypair, but when trying, for  
example, to encrypt data with the public key the card seems to throw  
and SW_UNSUPPORTED_FEATURE exception - this problem doesn't happen  
with 1024 bit keys.
2. The random number generator doesn't seem to work... (even though  
the card supports it).


I've been looking through the applet code, but can't find a reason why  
2048 bit RSA keys shouldn't work...

Can anyone help?

Regards,
Joao
