Encrypt more than 128 Byte of source data Using AES 128 on SE050

[mohamedaslam_m]

Hi Folks,

     I am using the SE050 development board for encryption purposes and I was checking the ex_symmetric example given in Plug and trust middleware. The example is given as 128 bits of Key, input data, and IV. 

How do we encrypt if we have more than 128 bits of input data?

Regards

Aslam

Hi @mohamedaslam_m ,

The following functions are provided for your case, the basic steps are init->update->update ... ->finish, as described in AN12413.

Hope that makes sense,

Have a great day,
Kan
