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.

Hope that is what you need.
