I have received the Fingerprint MOC Demo Kit (FS88H). Thanks for your J3H145 card.
But the package does not include any software CD that can let me download FPDemo.exe Application
How can I get this?

It seems that I found the problem. It is the conversion of the BigInteger value into a hex byte. I will try to fix this now.

I am trying to import a 1024 bit RSA private CRT key from a java application, but I cannot get it to work, I only got 6F 00 error code. Need it convert to hex-bytes? How do I convert it? Any help is much appreciated. Here is section of my code: final static byte SET_PRIVATE_KEY= (byte) 0x22; private...

I changed my encrypt method to this: private void encrypt(APDU apdu, byte[] dataToEncrypt, short len) { try { short outbytes; byte[] apduBuffer = apdu.getBuffer(); outbytes = cipher.doFinal(dataToEncrypt,(short)0, len, apduBuffer, (short)0); apdu.setOutgoing(); apdu.setOutgoingLength(outbytes); apdu...

My Java App creates a RSA-keypair. I send the public key to the card. The card generated 1 keypair before, too. Now the card sets another keypairs public key to the sent parameters, so that the card now can encrypt something for the offcard private key. Now I try to encrypt the parameters of the car...

Thank you for your kind answer, chico0609.

I have found the problem. It is surely caused by the PKCS1 padding.

I generate RSA Key and get Public Key from my applet. I encrypt "13131313131313130000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000" data with another tool with public key of my applet. My applet can decrypt this data perfectly....

Thank you for your help. Now I am confused about a basic question.
Does the java card API stored in a card in cap file form?

nikonai

I have to write a simple JCVM in C language,but I am experiencing a problem. Such as method invoke,if I invoke a method in a package,the byte-code is in the cap file. But if it is in JavaCard API like apdu.getbuffer(),how can I implement it? I just need to implement a simple version of JavaCard API,...

Great!! It works now. Thanks
