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: The different results with DES algorithm

I just found this description from the specification, which may explain the problem.

When non-block aligned data is presented as input data, no amount of input and output buffer data overlap is allowed; if inBuff==outBuff and outOffset < inOffset+inLength, incorrect output may result.

Re: Creation of a USB chip contact card product line at low cost

That would be good if there is a cheaper variant of eJava Token. Of course, this product might provide less resource than ejava token, such as smaller memory size..as tay00000 said.

Thanks for your quick response!

BTW, does A22CR card support TYPE_EC_FP_PRIVATE_TRANSIENT_DESELECT or TYPE_EC_FP_PRIVATE_TRANSIENT_RESET?

Buy A22CR cards

I am interested in buying some sample java cards for PKI. I thought A22CR cards may be suitable for our project.
Are there any minimum order quantities? Does A22CR card support Java Card 3.0.4? Does it support RSA4096? Thanks

Re: DES Encrypt/Decrypt

Is cipherText correct? As I know, one of the ILLEGAL_USE exception reasons is that padding is incorrect. I have crypted this byte[] plainText = {(byte)0x11,(byte)0x22,(byte)0x33,(byte)0x44,(byte)0x55,(byte)0x66,(byte)0x77,(byte)0x88}; with this key: byte[] key = {(byte)0x11,(byte)0x11,(byte)0x11,(b...
