If I understand this, you want to use a public RSA key to encrypt key material for export?
The applet doesn't support it, but you could extend the applet (and the supporting code) to do this... Look at the code for MSC_ExportKey as a starting point on the library side and at the corresponding code on the CardEdge.src/java side. You need to 1) Import an RSA public key to be the wrapper. 2) Create a javacardx.crypto.Cipher instance with one of the RSA encryption types and initialize it with the RSA public key 3) Encrypt the key material you want to export 4) Export the key data from the card to the application. One approach you might want to look at is http://www.ietf.org/internet-drafts/draft-ietf-smime-cms-rsa-kem-05.txt. This allows you to wrap any amount of data rather than being limited to data less than the length of the RSA key.
