PQC WireGuard with wolfSSL, We Can Do That!

WireGuard and Headscale / Tailscale don’t use Post-Quantum Cryptography. Adversaries recording that traffic today will decrypt it when quantum hardware arrives. The wolfCrypt PQC ML-KEM and ML-DSA implementations are production-ready, and FIPS validation is in process. We’ve already integrated post-quantum key exchange into TLS, DTLS, SSH, and MQTT. WireGuard is next. The engineering path is […]

wolfSSL vs MbedTLS – An apples-to-apples benchmark across Intel, ARM (Cortex-A and Cortex-M), and RISC-V targets.

Scope: the full wolfCrypt algorithm suite vs MbedTLS, measured the same way on four platforms (Intel x86_64, a Raspberry Pi 5 (ARMv8-A Cortex-A76), a bare-metal STM32H563 Cortex-M33, and a Microchip PolarFire SoC RISC-V U54), plus the post-quantum and extended-algorithm coverage MbedTLS does not have. wolfSSL v5.9.1, MbedTLS 3.6.6, June 2026. Method: identical sources built from […]

Maintaining FIPS Validation: Shifting from BitLocker to VeraCrypt with wolfCrypt

In September of 2026, the Cryptographic Module Validation Program (CMVP) will move all remaining FIPS 140-2 certificates to the Historical List, including the modules powering Windows BitLocker. For organizations navigating FIPS, CMMC, and FedRAMP, this is an immediate critical stop, as NIST guidance states federal agencies “should not include” Historical-status modules in new procurements, and […]

FIPS with Statically-Linked wolfSSL

Many FIPS deployments of wolfSSL’s FIPS 140-3 validated wolfCrypt module use dynamic linking to load the shared object / DLL. However, sometimes it is necessary for some types of projects to statically link the libwolfssl.a static archive directly into an executable or firmware image. This post explains why static linking takes a little extra care, […]

Introducing wolfHAL: A Lightweight Hardware Abstraction Layer for Embedded Systems

We are excited to announce wolfHAL, a new open-source project from wolfSSL. wolfHAL is a lightweight, OS-agnostic, compiler-agnostic hardware abstraction layer (HAL) for embedded targets, written in portable C. It sits between your application and the silicon, exposing a clean, uniform API for talking to peripherals such as GPIO, UART, SPI, I2C, DMA, flash, timers, […]
