java card- ECDSA signature
I have a java card. And I found that this card supports ECC over GF(p) for keys up to 320 bits and SHA-256 as well. Does this mean that the card supports ECDSA signature mode such as ALG_ECDSA_SHA256? Thanks for any help.

Re: Q with eJava Token
Hey guy.
ejavatoken can be used directly. It doesn't need any cards.
You can download and install your application into it, or any other operation.

Generate a key based on a byte array
There is a PIN in my applet, which is needed to encrypt by 3DES. I have a byte array "pw_ar" and I want to generate a key for 3DES algorithm based on this array. How can I do this? Thanks! Any reply is appreciated!
Note: my javacard version is JC2.1.1

Re: ECDSA signature
There is a step in the process of generating ECDSA signature - generate a random number, which causes different results.

Get 6982 during DAP verification
I want to load a cap file into the ISD. But when I added the DAP block linked to SSD in load command, it returns sw=0x6982.
Why do I get 6982? Is there something that I didn't pay attention to?
