Topic: Securing uTasker with wolfSSL

wolfSSL is happy to announce that the wolfSSL embedded SSL/TLS and wolfCrypt cryptography libraries have been ported to the uTasker operating system!

uTasker[1] is an operating system, stack, and collection of services designed for embedded devices.  It includes an OS, filesystem, device drivers, and TCP/IP stack among other features.  The uTasker package includes a device simulator, allowing developers to test and debug code faster than would be possible on physical hardware itself.  Complete details on the uTasker stack can be found on the project website:

wolfSSL has added a new preprocessor define to enable the uTasker port layer called WOLFSSL_UTASKER.  The port currently includes example client and server uTasker tasks which make use of the wolfSSL I/O abstraction layer to send and receive data over a secure SSL/TLS connection using uTasker RAW sockets.  The example tasks have been tested using the uTasker device simulator contained in the “uTasker_M522XX_V1.4-6” distribution.

What this means for projects using uTasker is that network connections can now communicate securely over SSL/TLS, using the progressive and lightweight wolfSSL SSL/TLS library.  Applications can also take advantage of the underlying wolfCrypt cryptography library to access crypto operations directly (block ciphers, stream ciphers, AEAD ciphers, hash functions, public key algorithms, and certificate verification routines).

The wolfSSL uTasker example client and server task are located in the ‘wolfssl-examples’ GitHub repository, linked below.  Documentation for these examples and on using wolfSSL with uTasker can be found on the wolfSSL website:
