Spring is here, and along with it is the newest and shiniest release of the wolfSSL embedded SSL/TLS library! As with every release, this release includes many feature additions, bug fixes, and improvements to the wolfSSL library. Additionally, this new version of the wolfSSL library includes support for the new FIPS 140-2 Certificate for wolfCrypt […]

The wolfSSL (formerly CyaSSL) embedded SSL library supports lwIP, the light weight internet protocol implementation, out of the box.  The user merely needs to define WOLFSSL_LWIP or uncomment the line /* #define WOLFSSL_LWIP */ in os_settings.h to use wolfSSL with lwIP. The focus of lwIP is to reduce RAM usage while still providing a full […]

Since earlier versions, wolfSSL’s embedded SSL/TLS library has been included with MPLAB Harmony. MPLAB Harmony is a flexible, fully integrated embedded software development framework for 32-bit MCUs and MPUs. Recently, MPLAB Harmony version 3 was released, with wolfSSL packaged within! The new release of MPLAB Harmony features aspects from the latest version of wolfSSL, version […]

wolfSSL provides many different products for many different implementations of internet protocols, one of which is wolfMQTT. The wolfMQTT library is a client implementation of the MQTT written in C for embedded use, with support for SSL/TLS via the wolfSSL library, and also provides support for MQTT-Sensor Network (MQTT-SN). While wolfMQTT is based on the […]

wolfSSL’s embedded SSL/TLS library has included support for TLS 1.3 since early releases of the TLS 1.3 draft. Since then, wolfSSL has remained up-to-date with the TLS 1.3 specification. In this post, the major upgrades of TLS 1.3 from TLS 1.2 are outlined below: TLS 1.3 This protocol is defined in RFC 8446. TLS 1.3 […]

Have you heard talk about SSL 3.0, TLS 1.0, TLS 1.1, TLS 1.2, and TLS 1.3 but never really knew the differences between the different versions? Secure Socket Layer (SSL) and Transport Security Layer (TLS) are both cryptographic protocols which provide secure communication over networks. These different versions are all in widespread use today in […]

wolfSSL provides support on four levels, one of which is the 24×7 support level. This support level includes many key features not available on the others, such as an unlimited number of support incidents, around-the-clock support from dedicated members of the wolfSSL support team, and remains in effect for an entire year. wolfSSL provides three […]

wolfSSL is excited to announce support for Espressif ESP32 hardware acceleration to the wolfSSL embedded SSL/TLS library! The ESP32-WROOM-32 is a powerful, generic Wi-Fi+BLE MCU module with high flexibility, and is easily interactable with the wolfSSL embedded SSL/TLS library. As wolfSSL is highly portable and the ESP32-WROOM-32 is highly flexible, if your application has any […]

wolfSSL embedded SSL/TLS support the latest Microchip ATECC508A and ATECC608A I2C cryptographic coprocessors. Not only is wolfSSL compatible with CryptoAuthLib, wolfSSL has also been tested on both the 508A and the 608A. Prerequisites: Requires the Microchip CryptoAuthLib (https://github.com/MicrochipTech/cryptoauthlib.git) Examples: wolfSSL uses PK (Public Key) callbacks for the TLS crypto operations wolfCrypt uses the WOLFSSL_ATECC508A macro […]

Recently, the National Institute of Standards and Technology (NIST) completed the validation of the wolfCrypt module version 4 for an updated Federal Information and Processing Standards (FIPS) 140-2 certificate. This new certificate includes updated and more secure algorithms added to the wolfCrypt module’s boundary, some of which are listed below. FIPS 140-2 is a government […]
