Re: Encounter error 6F 00 when importing RSA Private Key

Firstly you should find out which line throws the exception by using try/catch clause.

Re: How to reset card during APDUs execution

I think, there is no way for an applet to reset the card. You can try to do something from the reader side.

Re: overhead of creating byte arrays

I have seen some platforms that have a 7 bytes overhead for objects.

It's not specified. It really depends on the platform.

Re: generate RSA public and private key

The reason that you got 6F 00 is because there is un-handled exception in your code. Use try/catch statements to catch exception and find out exception reason.

Moreover, it turns out that ALG_RSA_CRT is the same as ALG_RSA, so if there is something wrong with ALG_RSA, just use ALG_RSA_CRT.
