The wolfSSL embedded TLS library has support for most of the STM32 microcontrollers and for their hardware-based cryptography (AES/HASH/PKA) and random number generator (TRNG). Here are the STM32 processors we currently support: STM32F2 STM32F4 STM32F7 STM32F1 STM32L4 STM32L5 STM32WB STM32H7 STM32G0 STM32U5 STM32H5 wolfSSL offers STM32Cube Expansion Packages for the STM32 toolset, letting users pull […]

wolfSentry, wolfSSL’s embedded firewall and IDPS, now supports out-of-the-box integration with lwIP! After simple initialization calls at application startup, all network traffic is evaluated and subject to filtration by the wolfSentry engine.  Prefiltering by network layer, protocol, and event type, allows zero-overhead transparency for selected traffic.  For example, TCP connection requests, inbound and/or outbound, can […]

One of the earliest posts on our blog is this one: https://www.wolfssl.com/wolfssl-supports-the-rim-playbook/ In 2010 it was announced that wolfSSL supported (Research In Motion) RIM’s BlackBerry Playbook and mentions QNX support ever since the first source release of wolfSSL.  That has been close to 20 years of support. In this post we’d like to mention that […]

With the myriad of options available for a bootloader today many integrators try and fail to find the most secure and flexible bootloader with the smallest footprint. To help put an end to this search we will be going over wolfBoot’s many advantages compared to its competitors to make clear why wolfBoot is the best […]

Recent research from Universidade do Minho in Portugal was presented at the Black Hat Asia conference in Singapore. The work of Dr. Sandro Pinto and Cristiano Rodrigues brought to the surface a groundbreaking technique that exploits the shared pipeline on the newest Cortex-M CPUs to place a time based, side-channel attack from an application running […]

Around the end of last year, Amazon announced MQTT v5.0 support for its AWS IoT Core MQTT Broker. Support for this protocol was added to the AWS wolfMQTT client example with a recent effort here at wolfSSL. The wolfMQTT library is a client implementation of MQTT written in C for embedded use, with support for […]

WolfSSL will attend Xponential at booth 3014 May 9th to May 11th in Denver, CO. At Xponential 2023, the focus is on new developments in unmanned vehicle systems. WolfSSL offers highly optimized TLS and cryptography libraries that secure IoT devices and embedded systems against cyber attacks. At both tradeshows, the wolfSSL team will meet with […]

wolfSSL is extremely proud to announce that an additional 18 OEs (Operating Environments) have been added to cert #3389 with only a 62-day turnaround from the CMVP between submission and approval: Feb 23 2023 – April 26 2023. INFO: Cert Location: https://csrc.nist.gov/projects/cryptographic-module-validation-program/certificate/3389 SunSet Date: 3/3/2024 Operating Environments validated (raw count): 73 Operating Environments validated (non-PAA […]

The cryptography world is abuzz with the new proposed NIST standard, Ascon. Earlier this year, NIST selected the Ascon family “for lightweight cryptography applications as it meets the needs of most use cases where lightweight cryptography is required”. More details can be found at the NIST News Update. We at wolfSSL have been testing an […]

Have you heard the news from the OpenSSL blog?  If you are using the 1.1.1 branch of releases of OpenSSL, come September 11, 2023, there will be no more updates. You can get the details here:  https://www.openssl.org/blog/blog/2023/03/28/1.1.1-EOL/    That said, you can breathe a sigh of relief because wolfSSL is here to help.  We have three […]
