Integrate robust security into your embedded systems without sacrificing functionality or performance.
  • Reduced Power Consumption: Minimizes power consumption, making it ideal for battery-powered devices and applications where extending battery life is critical. View our benchmarks.

Streamlined Development & Integration

  • Simplified Development: wolfSSL provides documented and user-friendly API, allowing developers of all experiences to quickly and easily integrate secure communication into their projects.
  • OpenSSL Compatibility Layer: For those familiar with OpenSSL, wolfSSL offers a compatibility layer that simplifies the transition, reducing development time and effort.
  • Industry Leading Support: All of our products are backed with up to 24/7 support from our engineering team.
  • Winbond Hardware Security for Secure Firmware Updates: wolfSSL supports Level Metering Scheme (LMS) compatibility. This allows wolfSSL to work with Winbond hardware-based LMS to ensure the authenticity of a firmware image during over-the-air (OTA) updates for an IoT target device. An IoT device typically uses Winbond flash memory for storage and runs wolfSSL for security. With this compatibility, the device can verify the firmware update it receives is genuine and hasn’t been tampered with before installing it. This helps to protect the device from unauthorized modifications and potential security risks. Additionally, wolfSSL can provide the secure TLS or DTLS connection to the cloud and use wolfMQTT to manage the FW update. In combination with Winbond’s ongoing hardware crypto validation, wolfSSL can deliver FIPS 140-3 compliant solutions for customers demanding the highest security and compliance.

wolfSSL Support for DO-178C DAL A

Enabling Secure Boot & Secure Firmware Update for Avionics

  • RTCA DO-178C level A certification.
  • wolfSSL offers DO-178 wolfCrypt as a commercial off-the-shelf (COTS) solution for connected avionics applications.
  • Adherence to DO-178C level A is supported through the first wolfCrypt COTS DO-178C certification kit release that includes traceable artifacts for the following encryption algorithms:
    • SHA-256 and SHA-384 for message digest.
    • AES for encryption and decryption.
    • RSA to sign and verify a message.
    • ChaCha20-Poly1305 for authenticated encryption and decryption.
    • ECC to sign, verify and share secrets.
    • HMAC for keyed-hashing for message authentication.
  • Provides the proper cryptographic underpinnings for secure boot and secure firmware update in commercial and military avionics.


TPM 2.0 designed for embedded use. wolfTPM is highly portable – written in native C, having a single IO callback for SPI hardware interface, no external dependencies, and its compacted code with low resource usage.

  • Open-source TPM 2.0 stack with backward API compatibility.
  • Native support for Linux & Windows.
  • RTOS and bare metal environments can use a single IO callback for SPI hardware interface, no external dependencies, and compact code size with low resource usage.
  • Offers API wrappers to help with complex TPM operations like attestation and examples to help with complex cryptographic processes like the generation of Certificate Signing Request (CSR) using a TPM.
  • Easy to compile on new platforms.


Client implementation of the MQTT written in C for embedded use.

  • Message Queuing Telemetry Transport is a lightweight open messaging protocol that was developed for constrained environments such as M2M (Machine to Machine) and IoT (Internet of Things), where a small code footprint is required.
  • Based on the Pub/Sub messaging principle of publishing messages and subscribing to topics.
  • The MQTT specification recommends TLS as a transport option to secure the protocol using port 8883 (secure-mqtt), as the MQTT protocol does not provide security on its own. Constrained devices benefit from using TLS session resumption to reduce the reconnection cost.
  • The wolfMQTT library is a client implementation of the MQTT written in C for embedded use. It supports SSL/TLS via the wolfSSL library. From this, it can provide the security that the MQTT protocol lacks.
  • Built from the ground up to be multi-platform, space conscious and extensible. Supports all Packet Types, all Quality of Service (QoS) levels 0-2 and supports SSL/TLS using the wolfSSL library. This implementation provides support for MQTT v5.0 and MQTT v3.1.1. Including client support for MQTT-SN (Sensor Network).


Lightweight SSHv2 server library written in ANSI C and targeted for embedded, RTOS, and resource-constrained environments – primarily because of its small size, speed, and feature set.

  • Commonly used in standard operating environments due to royalty-free pricing and excellent cross platform support.
  • wolfSSH is powered by the wolfCrypt library. A version of the wolfCrypt cryptography library has been FIPS 140-2 validated (Certificate #3389). For additional information, visit the wolfCrypt FIPS FAQ or contact fips@wolfSSL.com
