@ThePhoenyx
Do you have a special requirement for using the PKIApplet ?

Re: Suggestion for improving the JC10M128C

@JavaCardOS I do have an actual project requiring the above specifications thus my suggestions currently occurring on my end. Due to the lack of suitable cards meeting this requirement, I have to keep searching for reasonably priced cards that fit the above specifications. So far, the only cards I h...

Re: Suggestion for improving the JC10M128C

My applications usually would benefit from having 4 KB RAM while A22CR would only provide about 2.5 KB RAM thus my request to @JavaCardOS to possibly push for a card with around 4 KB RAM, have RSA support and at least 128 KB EEPROM/Flash or more at the very least.

Re: How to get mulitiple certificates from the applet

I will try to go to enough details without turning this into a spoon-feeding session. Create a class object called Certificate. This Certificate class will store a certAlias in byte[] object which you can allocate probably 10 bytes to use as certAlias as well as a certObject in byte[] object with pr...

Suggestion for improving the JC10M128C

I would like to suggest to @JavaCardOS to produce an improvement on the JC10M128C card. The card has much more superior RAM and a decent 128 KB Flash storage but it lacks RSA algorithm. I would like to suggest @JavaCardOS to produce their own more powerful smart cards in the category of a flagship s...

Re: 3DES

Please use the code block to encapsulate your codes. It is hard to read. /* * Collect the data to be MAC-ed in the array transaction_data */ private void computeAC(byte cid, byte[] apduBuffer, short length, byte[] response, short offset) { // Copy CDOL from the APDU buffer, at offset 0: Util.arrayCo...

Re: How to know which is my bR301

The best way to solve this problem is to loop through all the card readers, scan for the attached cards and each attached card must be provisioned with a UUID to identify itself. One way to do so is within the card applet to have a UUID where you will issue a UUID to each card during provisioning. O...

Re: A strange issue about JavaCard version

What is the applet you are trying to run or maybe provide a code sample and also the model and version of the card that is causing the problem.

Re: Random Data Genaration

I have no problem running your code fragment. Here's my process() method. public void process(APDU apdu) { if (selectingApplet()) { return; } byte[] buffer = apdu.getBuffer(); short bytesRead = apdu.setIncomingAndReceive(); if (buffer[ISO7816.OFFSET_CLA] == (byte) 0x00 && buffer[ISO7816.OFFS...

Re: How to put a string to my card

JavaCard datatypes are byte, byte[], short, boolean, some sort of Key related objects and sometimes certain cards come with int type. There is no such thing as String type. You have to convert String to byte[] before transmitting to card. Also, since you are new to JavaCard and probably smart card d...
