Deos is an embedded RTOS used for safety-critical avionics applications on commercial and military aircraft. Certified to DO-178C DAL A, […]

wolfBoot is wolfSSL’s own implementation of a secure bootloader that leverages wolfSSL’s underlying wolfCrypt module to provide signature authentication for the running firmware. The role of a secure bootloader is to effectively prevent the loading of malicious or unauthorized firmware on the target. Additionally, wolfBoot provides a fail-safe update mechanism, that can be interrupted at any time, and resumed […]

Some of the new additions include: support for port forwarding, client side pseudo terminal support, enhancements for non blocking use, AES-CTR cipher support, and support for SFTP on windows. This release also […]

With the release of wolfSSL 4.0.0, the wolfSSL team has also released a new product: the wolfSSL FIPS Ready library. This product features new, state of the art concepts and technology. In a single sentence, wolfSSL FIPS Ready is a testable and free to download open source embedded SSL/TLS library with support for FIPS validation, […]

wolfSSL can now be used to replace OpenSSL in WebSocket++! WebSocket++ is a header only C++ library that implements RFC6455 The WebSocket Protocol. It allows integrating WebSocket client and server functionality into C++ programs and uses interchangeable network transport modules including one based on raw char buffers, one based on C++ iostreams, and one based […]

The National Institute of Standards and Technology (NIST) has completed the validation of the wolfCrypt module version 4 for an updated Federal Information and Processing Standards (FIPS) 140-2 certificate in addition to its previous FIPS 140-2 certificate. This new certificate includes updated and more secure algorithms added to the wolfCrypt module’s boundary, some of which […]

Some interesting results were found when comparing the throughput of TLS 1.2 and TLS 1.3 using an assembly optimized wolfSSL – some good, some bad. This is the last of the blogs discussing the performance differences observed between TLS 1.2 and TLS 1.3 in wolfSSL and how to make the most of them in your […]

The wolfSSL embedded SSL/TLS library supports running on several Renesas platforms and has support for both the Renesas CS+ and e2 studio development environments. To make it easy to get started with wolfSSL, wolfSSL offers several example CS+ and e2 studio projects which can be run on a Starter Kit or Alpha Project board. The […]

TLS 1.3 has some significant changes from TLS 1.2 in the ordering of handshake messages and this impacts performance. This is the fifth part of six blogs discussing the performance differences observed between TLS 1.2 and TLS 1.3 in wolfSSL and how to make the most of them in your applications. This blog discusses how […]

The wolfSSL embedded SSL/TLS library features many different ports, including one for Apache Mynewt.
