For nearly 20 years, the wolfSSL library has set the benchmark for performant, full-featured cryptography and TLS transport on embedded targets. Since 2015, wolfSSL has been the premier FIPS-certified cryptography software module for the embedded space. Now, we bring that depth of experience to the Linux kernel. libwolfssl.ko implements the same comprehensive set of algorithms […]

Read MoreMore TagPDF Signing Meets FIPS-Capable PKCS#11: pdfsig + wolfPKCS11 + NSS
We’re excited to announce that the widely-used PDF signature tool pdfsig can now be used with wolfPKCS11 and NSS! This integration allows you to digitally sign PDF documents using PKCS#11 keys using software tokens, HSMs, or secure elements, through the NSS framework. All powered by the FIPS-ready wolfCrypt engine. Why This Matters For many applications […]
Read MoreMore TagBenchmarking Memory Usage in wolfCrypt Bench: New Heap and Stack Tracking Support
During a recent industry expo, the wolfSSL team demonstrated the wolfCrypt benchmark and received frequent questions about memory usage, particularly for post-quantum algorithms. We happened to be working on a feature which would provide exactly what was being asked for at the time, and I’m happy to report that it is wolfSSL’s GitHub repository now […]
Read MoreMore TagwolfSSL on Altera’s Cyclone V SoC FPGA
The Cyclone V, a cost-effective System-on-Chip (SoC) FPGA from Altera, combines a dual-core ARM Cortex-A9 processor (Hard Processor System, HPS) with a range of FPGA fabric configurations, tailored to specific family SKUs. It can be used with a variety of Real-Time Operating Systems (RTOS), including VxWorks, FreeRTOS, and Azure RTOS, as well as embedded Linux […]
Read MoreMore TagwolfDemo: A Passion Project Showcasing wolfSSL Technology
We love what we do at wolfSSL, to the extent that some of our official projects are even born out of personal side-projects. In that vein, I would like to introduce a demonstration board designed to showcase wolfSSL products at expos. A board we are calling “wolfDemo”. About Me For this blog post, I’m going […]
Read MoreMore TagwolfCrypt Rust Wrappers: Secure and Efficient Cryptography in Rust
We are thrilled to announce a significant enhancement to the wolfSSL repository: the addition of Rust wrappers for wolfCrypt! This integration, available now in our official wolfSSL GitHub repository, allows developers to leverage the robust cryptographic primitives of wolfCrypt directly within their Rust applications, benefiting from Rust’s safety, performance, and modern language features. Why Rust […]
Read MoreMore TagUpdated Xilinx/AMD Versal Benchmarks
There are three build options for crypto operations when using wolfSSL on Xilinx/AMD Ultrascale+ devices. The lightweight wolfSSL library can use a software only implementation, make use of the ARMv8 crypto extensions along with custom ARM assembly, or offload the operation to the CSU. Each has its trade offs. Recently wolfSSL has made improvements to […]
