At wolfSSL we’re excited about stateful hash-based signature schemes and the CNSA 2.0, and we just had a webinar on this subject. If you recall, previously we added initial support for LMS/HSS and XMSS/XMSS^MT, through external integration with the hash-sigs and xmss-reference implementations. Recently however we have completed our own wolfCrypt implementations of these algorithms, […]

wolfSSL on the Espressif ESP8266 – Better than ever!
It may not be as glamorous as the new ESP32 RISC-V chipsets with all the various hardware acceleration capabilities, but the ESP8266 is a well established device which has a large codebase available with an even larger user community. Due to high customer demand, we’ve enhanced the wolfSSL libraries for the ESP8266. The recent changes […]
Read MoreMore TagwolfSSL now supported on PlatformIO
The best encryption libraries are now available on the PlatformIO environment! At wolfSSL, we continue to embrace rapid prototyping environments, including Arduino, Visual Studio, and now PlatformIO for VS Code, among other IDE applications. There are hundreds of boards supported by PlatformIO on numerous frameworks and platforms. We are providing two different Official wolfSSL libraries: […]
Read MoreMore TagPQC support for the Zephyr port
PQC support for the Zephyr port was introduced in the last wolfSSL release using liboqs. This involved adding necessary files to the CMakeLists.txt for the Zephyr module. Zephyr is an open-source real-time operating system (RTOS) designed for resource-constrained devices and embedded systems. It is maintained by the Linux Foundation and supported by a vibrant community […]
Read MoreMore TagwolfSSL on Microblaze
MicroBlaze, developed by Xilinx, is a soft processor core optimized for Xilinx FPGAs. It offers flexibility and scalability, making it suitable for a wide range of applications, including embedded systems and IoT devices. Integrating wolfSSL’s AES-GCM with MicroBlaze is possible and has been done running on a soft CPU on MicroBlaze. In the latest wolfSSL […]
Read MoreMore TagRSA-PSS with CRL’s
Did you know wolfSSL has integration of RSA-PSS signatures with Certificate Revocation List (CRL) support? RSA-PSS: Enhancing Security Layers RSA-PSS, or Probabilistic Signature Scheme, represents a modern approach to digital signatures. Unlike traditional RSA signatures, RSA-PSS offers improved security properties, making it more resilient against various cryptographic attacks. By adopting RSA-PSS, wolfSSL users benefit from […]
Read MoreMore TagRemoval of user RSA
In the last release of wolfSSL there was some house cleaning done on older RSA implementations. The user RSA layer was removed along with the hooks used for tying in IPP. When those were first introduced we had yet to implement SP (single precision) versions of RSA. Fast forward to today, and there is a […]
Read MoreMore TagHow to unload intermediate certificates with wolfSSL?
Recently, a notable modification was introduced in wolfSSL, a prominent provider of security solutions. Pull request #7245 (https://github.com/wolfSSL/wolfssl/pull/7245) focuses on optimizing memory management by introducing a function to unload intermediate CA certificates and free up memory. Let’s explore the significance of this code change and its potential impact on enhancing efficiency and resource utilization within […]
Read MoreMore TagwolfSSL LTS Announcement
wolfSSL is announcing a long term support (LTS) version of the wolfSSL library. The goal of this product will be to provide users with fully ABI compatible releases of wolfSSL that are secure against all known vulnerabilities. Patches for vulnerabilities will be backported to the LTS branch in an ABI compatible way to guarantee security […]
Read MoreMore TagTLS on Embedded Systems: UART, I2C or SPI
Recently, we have seen an uptick in interest in securing communications between different embedded modules within a larger system. The academic community has seen great work in showing that these communications need to be secured; especially in the automotive space. Are you looking to start securing your internal communications over UART, I2C or SPI? With […]
