Get 0X6F00 with KeyPair(KeyPair.ALG_EC_FP,length)

[Vlidda]

I am stuck in a problem now. When I use KeyPair(KeyPair.ALG_EC_FP,length), it returns status word "0X6F00" ( unknown error ). Does it mean that my card doesn't support ECC? Or anything else?

It's more likely that your java card doesn't support the algorithm.

You can use try..catch statement to get reason codes.

Code: Select all

try{
  ....genKeyPair()
}
catch( CryptoException e ) {
        CryptoException.throwIt( e.getReason )
}
