Procedure for Sending AES-ECB Encrypted Data to STM32WLE5 for Decryption

[sandeep_kumar_v]

Hi,

I'm using two STM32WLE5 LoRa as TX and RX and added AES-ECB Encryption with Hardware Accelerator in the TX side and receive and decrypt it in RX side with the same Key. Now I want to change the TX module and want to implement same logic of AES Encryption in the TX side. Is there any documentation on how that can be implemented in the C/Python code for sending the same data with different module?

I have used PyCryptodome Python library for sending the data with encryption but it didn't work as expected. So, Is there any other library or documentation for implementing Encryption by which Receiver can be able to decrypt as before?

Configuration of AES in Both TX and RX sides

Any insights or guidance would be greatly appreciated.

Thanks in Advance.
