LMS in wolfPKCS11
wolfSSL is excited to announce upcoming support for the Leighton-Micali Signature (LMS) scheme in wolfPKCS11. This implementation builds upon our existing LMS support in wolfCrypt to provide a complete PKCS#11 API interface for LMS operations.
LMS, a stateful hash-based signature scheme standardized in RFC 8554 and approved by NIST SP 800-208, is already incorporated into the latest version of the PKCS#11 specification. This quantum-resistant signature scheme is designed to be resistant to attacks from quantum computers and is best used in off-line signing operations such as firmware signing.
The addition of LMS support to wolfPKCS11 will enable applications using the PKCS#11 interface to leverage wolfSSL’s proven LMS implementation.
Key Features:
- Complete PKCS#11 API support for LMS operations
- Quantum-resistant stateful hash based signature scheme
- Compliant with NIST SP 800-208 specifications
This enhancement demonstrates wolfSSL’s continued commitment to providing comprehensive support for post-quantum cryptography across our product line.

Announcing WebSocket Support in wolfMQTT
We are excited to announce that wolfMQTT now fully supports MQTT over WebSockets, including both standard WebSockets and secure WebSockets (WSS). Read more about websockets here. This significant enhancement allows wolfMQTT clients to connect to MQTT brokers through WebSocket endpoints, expanding the versatility of our lightweight MQTT client implementation.
Why Websockets Matter for MQTT
WebSockets provide several advantages for MQTT deployments:
- Firewall Traversal: WebSockets operate over HTTP ports (80 and 443), which are typically open in most network environments, allowing MQTT traffic to pass through firewalls that might block traditional MQTT ports.
- Web Integration: WebSockets enable seamless integration between web applications and MQTT, making it easier to build web-based IoT dashboards and control interfaces.
- Proxy Compatibility: WebSockets can work through HTTP proxies, extending the reach of MQTT in corporate environments.
- Enhanced Security: Secure WebSockets (WSS) leverage TLS encryption, providing the same level of security as MQTT over TLS.
The WebSocket implementation has been tested with popular MQTT brokers including:
- Mosquitto
- HiveMQ
- VerneMQ
The addition of WebSocket support to wolfMQTT enhances its versatility and makes it even more suitable for a wide range of IoT applications, especially those that need to operate in restricted network environments or integrate with web applications.
This feature is available now in the latest version of wolfMQTT. We encourage our users to try it out and provide feedback. As always, we’re committed to maintaining the lightweight, secure, and efficient nature of our MQTT client implementation while expanding its capabilities.

Visual Studio Support for Non-Windows OS in wolfSSL
Expanding Cross-Compilation Capabilities in Visual Studio
With the recent release of wolfSSL, we have significantly improved the cross-compiling capabilities of wolfSSL in Visual Studio, particularly when targeting non-Windows operating systems from a Windows-based development environment. This improvement was introduced in PR #7884 and provides a new build option that makes cross-compilation smoother and more efficient.
Introducing WOLFSSL_NOT_WINDOWS_API
One of the key additions in this release is the new macro WOLFSSL_NOT_WINDOWS_API. This is specifically designed for scenarios where:
- The compilation is performed on Windows using Visual Studio.
- The target operating system is not Windows.
- The Windows API should not be used during compilation.
When WOLFSSL_NOT_WINDOWS_API is defined, the related macro USE_WINDOWS_API is not defined, ensuring that wolfSSL is built under the assumption that no Windows API functions are available. This allows developers to cross-compile for platforms such as Linux or embedded systems while using Visual Studio as their primary development environment.
Why is this Important?
In many embedded and IoT use cases, developers prefer to work within Visual Studio due to its powerful debugging and development tools. However, the final deployment target may be a non-Windows OS. Prior to this update, Visual Studio builds often assumed that Windows API functions were available, leading to compatibility issues when targeting platforms that do not support them.
With WOLFSSL_NOT_WINDOWS_API, these limitations are removed, making it much easier to:
- Compile wolfSSL for embedded Linux and other POSIX-based environments from Windows.
- Maintain a single development workflow without switching between build environments.
- Ensure consistent behavior across different platforms.
How to Use WOLFSSL_NOT_WINDOWS_API in Your Build
To leverage this new macro, follow these steps:
-
Modify Your Preprocessor Definitions:
In your Visual Studio project settings, navigate to:- Configuration Properties → C/C++ → Preprocessor → Preprocessor Definitions
- Add
WOLFSSL_NOT_WINDOWS_APIto the list.
-
Use CMake (if applicable):
If you are using CMake for your build configuration, you can define this macro using:add_definitions(-DWOLFSSL_NOT_WINDOWS_API)
- Manually Define in Your Code (not recommended):
You can also define the macro at the beginning of your source files, though this is not the preferred method:#define WOLFSSL_NOT_WINDOWS_API #include
#include
Example Use Case: Building wolfSSL for Linux from Visual Studio
Let’s say you want to compile wolfSSL in Visual Studio for a Linux-based target while avoiding Windows API dependencies. Here’s a step-by-step approach:
- Set Up Your Toolchain
Install a cross-compilation toolchain for Linux, such as MinGW-w64 or WSL with a Linux cross-compiler. - Update Your Visual Studio Project Settings
- Define
WOLFSSL_NOT_WINDOWS_APIin preprocessor definitions. - Ensure that your include paths point to the correct non-Windows headers.
- Define
- Compile and Verify
- Build the project in Visual Studio.
- Test the generated binary on the target Linux system to ensure it operates correctly.
Future Enhancements and Next Steps
This update is just the beginning of improving wolfSSL’s cross-compilation capabilities within Visual Studio. Some potential future enhancements include:
- Better integration with CMake toolchains for automated cross-platform builds.
- Expanded CI/CD support for Visual Studio-based cross-compilation.
- Additional optimizations to streamline the build process further.
Conclusion
With the introduction of WOLFSSL_NOT_WINDOWS_API, developers can now cross-compile wolfSSL in Visual Studio for non-Windows targets without encountering Windows API dependencies. This simplifies the workflow for embedded and Linux developers who prefer to work in Visual Studio but deploy on other platforms.
