Description<br />
0 0 16 byte key<br />
1 8 byte key<br />
1 - 7 RFU<br />
In case of an 8-byte key, the first 8 bytes of the key data are valid.<br />
Mifare key<br />
Only the first 6 bytes of key data are valid.<br />
Number of stored keys<br />
The key management is able to store up to 32 keys.<br />
Encryption<br />
Key Data for DESFire and Mifare keys has to be encrypted with the login key in CBC<br />
mode. my-d S keys are enciphered every 8 byte block separately without CBC mode.<br />
CBC mode<br />
The data stream has to be divided into blocks of 8 bytes. The last enciphered block<br />
has to be XORed with the next plain block.<br />
