And then refer to the NEO IDG excerpt below for the definition of the response data:
For example, the response highlighted in the screenshot above for the data key slot (05) is "01443054453030", below is the breakdown with meanings:
01 - a valid key exists in key slot 5 which is the data encryption key
4430 - this is "D0" in ASCII means the key is used to encrypt data
54 - This is "T" in ASCII means the reader is on the TDES encryption algorithm
45 - This is "E" in ASCII means the key is for Encryption only
...
verify TDES/AES mode, send the c7-33 command via SDK Demo by following the steps below:
...
In the above example, the result is 00 (as shown in step 7), it's on TDES, if it's 01, then it's on AES.
2. To check whether a data encryption key is injected, send the 81-02 command with no data by following the steps shown in the screenshot below:
...
Check the 6th byte (key slot 5) in the Results window, if it is "01", that means the data encryption exists; if it's "00", no data encryption key is injected.
