meta-wolfssl

This layer provides a bbappend file for configuring cURL with wolfSSL. The wolfSSL recipe can be located here.

wolfSSL (formerly CyaSSL) is a lightweight SSL/TLS library written in C and targeted at embedded and RTOS environments - primarily because of its small size, speed, and feature set. With common build sizes between 20-100kB, it is typically up to 20 times smaller than OpenSSL. Other feature highlights include support for TLS 1.2 and DTLS 1.2, full client and server support, abstraction layers for easy porting, CRL and OCSP support, key and cert generation, and much more. For a full feature list, please visit the wolfSSL webpage at:

Setup

For detailed image writing and installation instructions, see our Beginner's Guide.

Clone meta-wolfssl onto your machine.

After installing YoctoProject/OpenEmbedded components and then running their build command:

  1. Insert the meta-wolfssl file location into the build's bblayers.conf file in BBLAYERS ?= "" section.

  2. Edit the build's local.conf file to include this line:

    IMAGE_INSTALL_append = " wolfssl" (include benchmark and/or wolfcrypt test recipes if needed)

  3. Edit an image file to include this line:

    IMAGE_INSTALL += "wolfssl"

Once you have built your image, the location on the new machine for wolfssl will be in /usr/libs, while benchmark and wolfcrypt will be located in /usr/bin.
