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 […]
