wolfSSH 1.4.18 Now Available!

    • It is Christmas in July! The summer release of wolfSSH is here, version 1.4.18!

    Version 1.4.18 brings with it bug fixes, new features, and some enhancements as well! New features in this release include new algorithms and a memory configuration option.

    We also have a nice round of enhancements which range from channel setup callbacks, better testing, improved portability, and more!

    New Features

    • wolfSSL style static memory pool allocation support.
    • Ed25519 public key support.
    • Banner option for wolfSSHd configuration.
    • Non-blocking socket support to the example SCP client.

    Improvements

    • Documentation updates.
    • Update the Zephyr test action.
    • Add a no-filesystem build to the Zephyr port.
    • Update the macOS test action.
    • Refactor certificate processing. Only verify certificates when a signature is present.
    • Update the Kyber test action.
    • Refactor the Curve25519 Key Agreement support.
    • Update the STM32Cube Pack.
    • Increase the memory that Zephyr uses for a heap for testing.
    • Add a macro wrapper to replace the ReadDir function.
    • Add callback hook for keying completion.
    • Add function to return strings for the names of algorithms.
    • Add asynchronous server side user authentication.
    • Add ssh-rsa (SHA-1) to the default user auth algorithm list when sha1-soft-disable is disabled.
    • Update Espressif examples using Managed Components.
