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: What I could make, after I learned STM32.

You can create a embedded hardware to read ISO7816 cards and ISO14443 cards or you can create your own embedded security test demonstrator kit as a few examples if you are trying to do security demonstration and testing. There is a lot of use cases and you have to find out what you really want to do...

Re: RSA 4096 sample data for test(public key,private key, ciphered data)

I would strongly recommend you to use either BouncyCastle or Java JCE to generate sample RSA-4096 enciphered data and test. Also, I would recommend you look into the US NIST's Known Answer Test which is a bunch of sample known test data. Link: https://csrc.nist.gov/projects/cryptographic-algorithm-v...

Re: implement x.509 certificate

Do you mean creating the X.509 certificates from within the smart card after the smart card have generated a keypair ?

Re: AES

Here are the generic steps for you to encrypt your APDU commands. Firstly, you can use the card's SCP protocol to open a secure channel into the card but it seems like from your question, you are more interested in creating your own secure channel so we will assume you want to make your own encrypte...

Re: Searching for java card that supports BIP 0039, BIP0042, ed25519

Sorry, you will not be able to find X25519 capable algorithms on any JavaCard. The simple reason is JavaCards up till now are struggling hard to get NIST Fp and Fm curves with some cards having some NIST curve support and others preferring other NIST curve support depending on vendor. X25519 being n...

Re: Smart Card Fido U2F Applet

Probably some side knowledge in case people are wondering. I was reading something regarding how Windows handles USB drivers and it doesn't allow HID, CCID and mass storage access via the default Windows driver and thus Zadig must be used to swap out for a USB driver that allows WebUSB. So no go for...

Re: Smart Card Fido U2F Applet

I know that this is a rather old topic so probably I might be missing something. I am recently deciding to test out U2F applet by @Javacardos and also the cards bought from @Javacardos. Applet installed on card with no problems. When I insert card into card reader and visited Yubico's U2F demo page ...

Re: Smart Card Gids Applet

OpenSC is a framework and requires developers to write plugins to submit to OpenSC to include into their toolkits and libraries. From OpenSC's Github source codes, it seems that GIDS support over PKCS15 is available. Which flavour of GIDS applet are you using ? Which card are you using ? Do provide ...
