Secure Email Client with Freescale KSDK + wolfSSL + FRDM-K64F

Are you interested in having a secure email client on your Freescale Kinetis device? How about one that uses wolfSSL too!

A member of the Freescale/NXP community (Denis Shimizu) recently adapted the original SMTP protocol implementation that is included with KSDK 1.3 to add in secure connections using the wolfSSL lightweight SSL/TLS library.

The example software is currently ported to the FRDM-K64F Kinetis board, but can be implemented on other boards as well. This demo sends an email using the GMail SMTP server (, port 465) through a secure SSL/TLS channel.

For the details and code, please visit the following page on the Freescale/NXP Community website:

wolfSSL has been ported to the Freescale Coldfire and Kinetis processors, and can take advantage of the hardware cryptography offered by the CAU, and mmCAU.
