yaSSL is happy to announce that the CyaSSL embedded SSL library now supports MQX/RTCS/MFS as well as the Kinetis MCU and H/W RNGA.  To supplement the port, we have also released several example CodeWarrior projects for CyaSSL. Please read the blog post on the subject for details: Security on Freescale Kinetis MQX with CyaSSL.


CyaSSL is dual licensed under both the GPLv2 and standard commercial license and has been optimized for use in resource constrained environments.  The most up-to-date code can be found in the CyaSSL GitHub repository, here: cyassl/cyassl · GitHub


When building CyaSSL for MQX, you'll need to uncomment the FREESCALE_MQX define found in <cyassl_root_dir>/cyassl/ctaocrypt/settings.h.  In addition to supporting MQX, CyaSSL supports a long list of platforms and is generally very easy to port to new environments as well.  Please let us know if you have any questions or feedback on our CyaSSL MQX port.  You can reply to this thread, or email us directly at
