RSA Encryption
843851Dec 9 2009 — edited Dec 12 2009Hi, I'm new here and also beginner in java card programming.
I have some doubts. In java card API there are classes providing RSA encryption/decryption. And here goes my question:
- do those algorithms require a card? (either virtual or real). If not - how to use smartcards to encrypt data?
My problem is that I need to create application providing message encryption using RSA with key stored on smartcard. Since It's rather magic for me, I need a hint how to do this. In all examples, there is APDU and connection between card and application. But all transmission vanish as the RSA encryption comes. It' really confusing.
I would be very appreciated for any help.
Cheers,
sonic
