wolfSSH

Introduction

wolfSSH is a lightweight, portable SSH library optimized for embedded systems, RTOS environments, and resource-constrained devices. It provides secure shell functionality including SSH server and client implementations, SCP, and SFTP support. Its support for multiple build configurations makes it suitable for a wide range of applications and hardware platforms that are utilizing Zephyr RTOS.

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

wolfSSH is dual licensed under GPLv3 and commercial licenses.

Requirements

  • wolfSSL for cryptographic operations

Usage with Zephyr

Add wolfSSH as a project to your west.yml:

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

Update west’s modules:

west update

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