wolfIP now includes native wolfGuard support, bringing a FIPS-compliant WireGuard VPN tunnel directly into the stack. wolfGuard replaces the standard WireGuard cipher suite (Curve25519, ChaCha20-Poly1305, BLAKE2s) with FIPS-certified alternatives (P-256 ECDH, AES-256-GCM, SHA-256) using wolfSSL cryptographic primitives, while preserving the Noise IKpsk2 handshake and its security properties including perfect forward secrecy and automatic key rotation.

New Migration Guide: Moving from lwIP to wolfIP
Do you use lwIP today and want a more deterministic networking stack for embedded, real-time, or safety-critical systems? We just published a new developer guide: **Migrating from lwIP to wolfIP**. wolfIP is designed around a simple idea: connected embedded systems should keep networking resources under control. Instead of relying on dynamic allocation and runtime growth, […]
Read MoreMore TagwolfIP TCP/IP Stack on the LPC54S018
wolfSSL is announcing wolfIP support for NXP LPC microcontrollers, starting with the LPCXpresso54S018M development board (LPC54S018J4M). This is the first NXP platform supported by wolfIP, extending coverage beyond the existing STM32 and VORAGO VA416xx ports. wolfIP provides DHCP, ICMP ping, and a TCP echo server on this new platform. About the LPC54S018 The LPC54S018 is […]
Read MoreMore TagwolfIP TCP/IP Stack on the STM32N6
wolfSSL is announcing wolfIP support for the STM32N6 series, starting with the NUCLEO-N657X0-Q development board (STM32N657X0H). The STM32N6 is ST’s first Cortex-M55 microcontroller, designed for high-performance edge AI workloads with a dedicated Neural Processing Unit (NPU). wolfIP provides a full TCP/IP stack with ping, TCP echo, and ARP on this new platform. About the STM32N6 […]
Read MoreMore TagSimplified Networking: wolfIP Now Supports STM32CubeMX
Developing robust, secure networking for embedded systems just got a whole lot smoother. We are excited to announce that wolfIP now features official STM32CubeMX Pack support. Manual integration of networking stacks can be a headache, often requiring tedious porting and configuration. By introducing this CubePack, we’ve bridged the gap between the wolfIP stack and the […]
Read MoreMore TagTLS vs. SSH: When To Use Which (2026 Edition)
TLS and SSH are both widely used protocols for creating secure connections between two systems over an untrusted network. Although they share some fundamental goals, they are designed for different use cases. In this updated guide, we will explore when you should use which, along with a look at the latest developments in both protocols. […]
Read MoreMore TagA Second Helping of Security for the Raspberry Pi Pico
Last year, we wrote about the support we added for the Raspberry Pi Pico in wolfSSL. Since then, we haven’t been sitting idle. The wolf pack has been busy adding even more security goodness to the Pico ecosystem. If you thought TLS on a $1 microcontroller was impressive, wait until you see what we’ve been […]
Read MoreMore TagwolfIP – Adds TLS 1.3, SSH, and MQTT Support for STM32H563
As the demand for secure embedded connectivity grows, the need for robust, lightweight protocols on bare-metal systems becomes critical. wolfSSL is proud to announce that wolfIP now includes comprehensive secure communication support for the STM32H563 (NUCLEO-H563ZI) board, bringing modern security standards to your bare-metal applications. This update introduces full integration with wolfSSL, wolfSSH, and wolfMQTT, […]
Read MoreMore TagwolfIP 1.0.0 Released: Deterministic TCP/IP for Embedded and Safety-Critical Systems
We are excited to announce the release of wolfIP 1.0.0, the first public release of wolfSSL’s lightweight TCP/IP stack for embedded, real-time, and safety-critical systems. wolfIP is built around a simple idea: networking behavior should be defined before runtime, not discovered during it. With no dynamic memory allocation, fixed socket tables, pre-allocated packet buffers, and […]
Read MoreMore TagIntroducing wolfIP: a tiny, safe TCP/IP stack for embedded and safety critical systems
If you have ever tried to drop a full networking stack into a deeply embedded target, you know the drill: memory budgets get tight, timing gets unpredictable, and dynamic allocation can turn certification efforts into a slog. wolfIP is our answer: a compact TCP/IP stack that favors determinism over surprise, and standard interfaces over complex […]
