Our Online Store have the new products: RFID antenna board. Currently it can work with JC10M24R and JCOP4 card chips.
Compared with normal cards, the antenna board module has a smaller size and fixed holes, which is easy to integrate in the IOT(Internet Of Things) project.

Re: Get CryptoException.ILLEGAL_VALUE when generating ECC key pair

For JCOP card, you should set ECC domain parameters for both the public key and private key before genKeyPair() . FYI: Check the code below to set the parameters. pubKey.setFieldFP(p, (short) 0, (short) p.length); pubKey.setA(a, (short) 0, (short) a.length); pubKey.setB(b, (short) 0, (short) b.lengt...

Tokens are required when the Issuer Security Domain ...

Re: Is there any AES keys with 192 and 256 bits

The cipher object does not have a key size attribute. Only the key object has the key size. You can use an AES cipher with all the three key sizes.

Re: Got 0x6444 when calling buildKey()

Maybe you should try to use RSA1024 or RSA512. It may be a problem with supported algorithms and non-standard response codes.

Re: Get a CryptoException when creating signature

Remember to initialize the signature instance with a signing key.

If convenient, could you post the complete code of your applet?

Re: write an applet for automatic switch Dual IMSI

A1:
Roaming is detected when current MCC and MNC is different with Home MCC and MNC, then the applet may decide to switch or not based on the requirement.
A2:
You can check the related specification defined by telco operator!

Re: Load mifare application to dual interface java card

These are pseudo APDUs interpreted by the smart card reader. The mifare protocol is special, it has nothing to do with APDU.

BTW, if your java card supports mifare, ask the card manufacturer to assist you on how to access the mifare memory zone from javacard.

Re: I got 0x6985 and 0x611C from my java card in different scenario.

Hi @ horse dream. Thank your for your answer. But I know this. My main question is why I got different status word("6985", "611C") when I send the same command via my java code and APDUTool. For java, there is a "feature" in a package javax.smartcardio when it is worki...

Re: I got 0x6985 and 0x611C from my java card in different scenario.

When it returns "61 1C" response, you need to send "Get response" APDU command.
>> 00 C0 00 00 1C
