Re: [lwip-users] LWIP altcp_mbedtls webserver performance issue

[Amr Elsayed]

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.

mbedTLS does not use the hardware functions of this chip by default, you
need to add that by yourself (*). We do have a https webserver running on such
a chip at 80 MHz, so it should definitively be possible. We do have an external
helper chip doing the RSA though...

(*) you might find examples for STM in the embed-os repository

Simon
