    After I lost a few charges, I think I understand how to change Master Key and Application Key.
    But I still would like to confirm one more thing.

    What KeyType would you use to change from NEW_KEY_AES TO ANOTHER_NEW_KEY_AES.

    If I use KeyType.AES128, I can no longer authenticate with either new key or old key.

    Possible bug?

    In this case, you should show how to change DEFAULT KEY TO AES in your example. Can you show me how?
    If I need data sheet to understand, SDK should clearly mention about it in my opinion. Otherwise, it is waste of time for developers.

    Hi,

    I was able to change the key once using with KeyType.TWO_KEY_THREEDES 16 byte.

    1. Never able to change the key with 24 byte.

    public static final byte[] DEFAULT_KEY_2KTDES_16 = {
    (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00,
    (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00,
    (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00,
    (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00};

    final Key AUTH_KEY = new SecretKeySpec(DEFAULT_KEY_2KTDES_16, "DESede");

    iDESFireEV1.changeKey(0, KeyType.THREEDES, DEFAULT_KEY_2KTDES_16,
    SampleAppKeys.TEST_MASTER_KEY_2_2KTDES_16, (byte) 0);

    2. I am able to authenticate with a new key after changeKey.

    3. I want to change MasterKey again. From DEFAULT_KEY_2KTDES_16 to a new keyType with THREEDES OR KTHREE_KEY_THREEDES OR AES128.
    NEVER SUCCESS.

    Hi @TapLinx Support,

    Is it possible to change DEFAULT MASTER KEY which is all zero to KeyType.AES128 ?
    If so, can you provide code snippet?

    I am getting integrity error.

    Hi,

    Current SDK need Internet access to register lib and also collect usage information via google analytics.

    Do you have a paid version of SDK without those?

    I have a project and I want to use TapLinx if possible.
