I want to decrypt a message, which is generated by a java application using public key. But it returned a ILLEGAL_VALUE error (e.getReason() = 1). The keys have been created in the java application. If I want to crypt and decrypt messages with a keypair created in the java card, it works fine. Any i...

I have the GP specification and I also checked it carefully. But i still don't know the calculation process. Can someone help me out?

I have a new blank java card, which is never used before. Now I have to create MF while connecting card. For all I know, this operation-creating MF can only be done one time. After this, I can not modify it any more, is it true?

Thanks for your help, wumindejia.

We have some experience with JCOP OS cards. But I want to find a cheaper variants now. We only need the card to support RSA and the EEPROM 20K is enough. Is there any cheaper cards for my requirement? Thanks

But I'm still a bit confused about this product. Should I also need to buy one special card to work with this token?

Or can I use it directly?

Thanks!

I am a bit confused about SELECT and DESELECT method. AWAK, we can select the applet in the applet itself. Actually, the JCRE is the one who perform applet selection. Thus I think that the implementation of SELECT should be in the JCRE. Am I right? I really want to know why SELECT method should be i...
