We have updated our Zephyr support to 3.4 for wolfSSL release 5.6.2! Zephyr is an open-source real-time operating system (RTOS). It is portable (supporting over 450 boards!) and secure with a comprehensive and lightweight kernel. All of these features make wolfSSL a great choice for security in Zephyr. The port update comes with a set […]

With our ongoing development of world-class commercial-grade cryptography solutions for the Espressif products, wolfSSL is proud to announce support for the ESP32-S3 Embedded Linux Kernel! Our very own [gojimmypi] was able to get the wolfSSL wolfcrypt tests running successfully as an app on the embedded Linux environment thanks to the work of [jcmvbkbc] on linux-xtensa. […]

A while back, we posted the following entry on our blog: https://www.wolfssl.com/wolfssh-post-quantum-interoperability-confirmed/ In it, we talked about post-quantum interoperability with both the OpenQuantumSafe’s OpenSSH fork and AWS’s implementation of SSH. More recently, our friends at AWS have posted a great set of detailed instructions on how to reproduce their interoperability test results: https://aws.amazon.com/blogs/security/post-quantum-hybrid-sftp-file-transfers-using-aws-transfer-family/ There, you […]

We are excited to tell you about our partner collaboration with ST Micro! This collaboration is a video series about wolfBoot, a secure bootloader and the STM32, a family of 32-bit microcontrollers. This is a 4 part video series showing how to use wolfBoot on various STM32 microcontrollers. Video 1: wolfBoot for STM32, Part 1: […]

One of the features that makes wolfSSL stand out from other SSL/TLS libraries is its wide range of support for many hardware cryptographic accelerators. In particular, wolfSSL leverages the cryptographic accelerators built into the NXP i.MX6 and i.MX8 processors. How it uses the CAAM with i.MX6 and i.MX8 is dependent on the OS being used, […]

Did you know that wolfSSL has been ported to and tested on Xilinx Versal hardware? There is support also in wolfSSL to make use of the Xilinx hardened crypto, enhancing both security and performance. Xilinx hardened crypto has accelerated crypto operations (SHA3-384 / AES-GCM / RSA / ECDSA) available on Ultrascale+ devices and is available […]

Would you like to learn more about how SSL/TLS work, or more about the wolfSSL lightweight SSL library? If so, wolfSSL is offering a training course on SSL/TLS and wolfSSL. The FREE 2 day (4 hours each day) wolfSSL training course covers details of SSL/TLS as well as the wolfSSL embedded SSL library. Participants will […]

As many people know, Chinese government regulators are now mandating use of SM2, SM3 and SM4 in critical systems, including automobiles, avionics, power systems, and communication systems.  Since many of our customers are multi-nationals that do business in China, they have been requesting the addition of these algorithms in wolfSSL products. Today we are about […]

wolfSSH 1.4.14 is now available for download! This is the next version of our lightweight, IoT friendly SSH implementation. There were some good fixes and improvements made to the code base for this release. A couple of the notable additions were: Adding user authentication support for RSA signing with SHA2-256 and SHA2-512 (Following RFC 8332) […]

Another new addition in our 5.6.2 release of wolfSSL is our TLS hardening option. This TLS hardening feature secures your TLS connections according to the recommendations in RFC 9325. When enabled, wolfSSL will: disable TLS versions older than 1.2 disable cipher suites based on ephemeral finite-field Diffie-Hellman key agreement finite-field Diffie-Hellman key agreement (i.e., “TLS_DHE_*” […]
