s32k144 CSEc CMD_ENC_ECB padding

[skseofh]

Hi

In s32k144 CSEc CMD_ENC_ECB, how can I make input data padding in the application(the data length is not a multiple of 128-bit).

example)

data : 01 02 03 04 05(5Byte)

- S32K144 RM page 885

Is it a PKCS #7 padding or just add 0s?

Hi,

you can use whatever you wish. It's up to you. Nice description can be found here, for example:
