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.

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 ...

Re: Random number generator

Your attempt to call ALG_TRNG is technically correct in the sense that is JC 3.0.5 specification API. The thing is if your card does not support JC 3.0.5, you are better off using ALG_SECURE_RANDOM and ALG_PSEUDO_RANDOM which is in the JC 2.2.X version of the API. Also note that ALG_SECURE_RANDOM an...
