Re: [Globalplatform-users] 2048 bits RSA keys

Thank you both for your suggestions and help. I have tried to move initialization of the RSA keys to a separate applet function, but it fails with the same error: The link http://sourceforge.net/p/globalplatform/wiki/GPShell/ contains several java cards which have been tested. Do you know if any of them has been tested with an initialization of a 2048 bits RSA key?

Subject: Re: [Globalplatform-users] 2048 bits RSA keys I think I've seen this one before. Try moving the creation of the RSA objects out of the install() method and the instantiation method. Instead, try this in a method that gets called after the applet is installed and as part of an initialization call. I don't know exactly what you're doing here, but if you're trying to generate a key pair as part of the install and make selectable, you're probably timing out and that's being read as a comms failure.

If some constraints like the required memory or instances of used algorithms are not satisfied, this error can result.
