Its a PKI encryption were the algo to encrypt and decrypt are the same, but the keys are different.
So to encrypt for the card you will need.
1. The Public Key (mod and exp)
2. The packet format
3. The actual PKI algo used (and any little tricks they may have done).
The card will then use the matching Private key (mod and exp) to reverse and use.
