Re: How do I create a certificate in javacard?

1 Generate keypair in the JavaCard;
2 Output the public key;
3 Build one certificate object with the public key and other informations using middleware;
4 Store the certificate object into the JavaCard, it can be directly readed from JavaCard next time it used.
I'll find code sample for you, wait me.

Re: Secure Messaging

1 Maybe you need the PIN verfied.
2 Maybe the command MAC is incorrect. Which tool are you using to send theses commands? The MAC of the READ BINARY command is calculated yourself?

Re: Transient reference to a byte array

You can store the reference to a array created by JC API: JCSystem.makeTransientObjectArray(...).
Hope that is what you need.

Re: ICC Master Key Derivation

Described in EMV 4.x Book 2, Chapter "Master Key Derivation", there's 3 methods to Generate MK.
And in the code of OpenEMV applet, the MK is a constant bytes, and it can be personalized before use it.
