How Can I Verify TDES/AES Mode and if a Data Encryption Key is Injected for VP3300? 

Answer:

1. To verify TDES/AES mode, send the c7-33 command via SDK Demo by following the steps below: 

Open

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:

Open

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.
