This one-day event offers hands-on workshops and technical lectures over multiple markets enabling attendees to customize a schedule that is most relevant to their training needs. Where wolfSSL […]

TLS 1.3 is the latest version of the SSL/TLS specification. There are significant changes to messages and the message flow. These changes are targeted at security and performance. The first performance difference to note is a degradation. In TLS 1.2 performing a resumption handshake is very quick. This comes at a security cost though. Each […]

People have been asking if wolfSSL is vulnerable to the ’Selfie’ attack (https://eprint.iacr.org/2019/347).  We are glad to say that we follow all the recommendations made by the authors.  First, though, an explanation of the attack. Overview The attack targets the use of Pre-Shared Keys (PSKs) with TLS 1.3 though TLS 1.2 is also vulnerable.  There […]

In a single sentence, wolfSSL FIPS Ready is a testable and free to download open source embedded SSL/TLS library with support for FIPS […]

Recently, we announced that there was support for JSSE in the works at wolfSSL. That project is currently nearing completion, and wolfSSL will soon be happy to announce its support for providing JSSE included with the wolfSSL-JNI library! Java Secure Sockets Extension (JSSE) is a way for Java applications to utilize the SSL and TLS […]

With the recent release of wolfSSL 4.0.0, the wolfSSL embedded SSL/TLS library comes with many new features and improved functionality. Among these features is the addition of a port to the Zephyr Project – a scalable real-time operating system (RTOS) supporting multiple hardware architectures, optimized for resource constrained devices, and built with safety and security […]

Are you a user of the ESP-IDF(Espressif IoT Development Framework)? If so, you will be happy to know that wolfSSL recently added support and example projects to the wolfSSL embedded SSL/TLS library for ESP-IDF. ESP-IDF is intended for rapidly developing Internet-of-Things (IoT) applications, with Wi-Fi, Bluetooth, power management and several other system features. The ESP-IDF […]

wolfSSL’s embedded SSL/TLS library provides support for many different features, such as TLS 1.3, a FIPS 140-2 validation, and even support for SSL/TLS using less traditional I/O.  In this context, “less traditional I/O” means running SSL/TLS over something besides TCP/IP or UDP – for example Bluetooth, a serial connection, memory buffers, or a proprietary transfer protocol. […]

Are you looking for an SSL/TLS library which will seamlessly integrate into your bare metal or No-OS environment? If so, continue reading to learn why the wolfSSL lightweight SSL library is a perfect fit for such environments. wolfSSL has been designed with portability and ease of use in mind, allowing developers to easily integrate it […]
