Introduction

---

wolfSSL is a lightweight, portable SSL/TLS library optimized for embedded systems, RTOS environments, and resource-constrained devices. It offers a range of cryptographic functions, and secure communication protocols (up to TLS 1.3 and DTLS 1.3) along with post-quantum cryptography support. Its support for multiple build configurations makes it suitable for a wide range of applications and hardware platforms that are utilizing the Zephyr RTOS.

wolfSSL has support for the Zephyr networking stack so applications can use the wolfSSL API to establish secure connections with other devices or services over the network.

wolfSSL is dual licensed under GPLv3 and commercial licenses.

Usage with Zephyr

---

Add wolfssl as a project to your west.yml:

.. code-block:: yaml

manifest: remotes: # <your other remotes> - name: wolfssl url-base: https://github.com/wolfssl projects: # <your other projects> - name: wolfssl path: modules/crypto/wolfssl revision: master remote: wolfssl

Update west's modules:

.. code-block:: bash

west update

Now west recognizes wolfssl as a module, and will include its Kconfig and CMakeLists.txt in the build system.
