    in reply to: Authentication Failed! MIFARE UltralightC
    Thank you so much, I finally could've Authenticated. I used your code but with this changes:
    /**************************/

    Key key = new SecretKeySpec(ULTRALIGHT_C_DEFAULT, "DESede");

    KeyData keyData = new KeyData();

    keyData.setKey(key);

    ulc.authenticate( keyData );

    /***************************/

    I didn't use SecureKeyGenerator because I was getting the same exception as you, but this works fine.
