Dear Simon,
Thank you for the response, Can you share with me the chip name for the RSA
? I have implemented  the cryptography hardware accelerators on mbedtls
library from ST examples, the accelerators are used in AES, DES, MD5, SHA1,
SHA256 , and Entropy for the random generator. that's why the encryption is
fast but the problem is only the Handshaking, as Far as I got, There's no
hardware accelerators examples from ST for RSA.

Thanks and Best Regards,
Amr Elsayed.
