Recently, wolfSSL released version 3.15.5 of the wolfSSL embedded SSL/TLS library. This new release features many new additions and updates, including the addition of a port for the STM32L4 MCU.
The STM32L4 is an ultra-low-power device with high flexibility, and as a member of the STM32 family, is easily integratable with the wolfSSL library. As wolfSSL is highly portable and the STM32L4 is highly flexible, if your device has any special features that interfere with the wolfSSL port, they are easily remedied.
The new wolfSSL STM32 port functionality was added into the existing STM32 port, and the STM32L4 functionality can be enabled by either defining the "WOLFSSL_STM32L4" option in the user_settings.h file, or by including the option CPPFLAGS="-DWOLFSSL_STM32L4" to the configure script if building the wolfSSL library with autotools.
Additionally, wolfSSL also provides support for the latest version of the TLS protocol, TLS 1.3! Find more information about TLS 1.3 here: https://www.wolfssl.com/docs/tls13/
