Hi @StephenYeh ,
Thanks so much for your cooperation with the new questions post. Welcome!
As I know, TLS 1.2 with RT1062 and AES128 can be supported.
You can refer to the RT1060 SDK demo:
\SDK_2_13_1_EVK-MIMXRT1060\boards\evkmimxrt1060\lwip_examples\lwip_httpssrv_mbedTLS
Wish it helps you!
If you still have questions about it, please kindly let me know.
Best Regards,
Kerry
