Re: wolfSSL on pic24

Hi,

We haven't tested wolfSSL on the PIC24 in house, but have had users run wolfSSL on a 16-bit platform before.  When compiling wolfSSL, you can define SIZEOF_LONG and SIZEOF_LONG_LONG to match your platform's sizeof(long) and sizeof(long long).

Have you tried this?

Best Regards,
Chris

Re: wolfSSL on pic24

UPDATE:

wolfSSL has tested on a PIC24 using the custom I/O Callbacks to perform a TLS connection over UART Serial.

The changes necessary to get the test running are in a temporary branch here:
https://github.com/wolfSSL/wolfssl/comp … g?expand=1

PIC24 is not supported out-of-the box at this time but if there are any customers interested in seeing out of the box support added for pic24 or 16-bit MCU please shoot us an email at support@wolfssl.com or info@wolfssl.com to let us know about your need.

Test was performed on an EXPLORER 16/32 using a PIC24FJ1024GB610 Plug in Module (PIM).

Cipher suites that were successfully tested are:

ECDHE-ECDSA-AES128-SHA256 - (TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256)
DHE-PSK-AES128-CBC-SHA256 - (TLS_DHE_PSK_WITH_AES_128_CBC_SHA256)
AES128-SHA - (Static RSA cipher suite: TLS_RSA_WITH_AES_128_CBC_SHA)

Test scenario was:

Client running on the PIC24
Server running on a host machine connected by UART Serial full-duplex
Client and server were able to successfully perform a TLS handshake and pass encrypted application data over the UART serial connection.
