wolfSSL Yocto Project and OpenEmbedded Support

Did you know that wolfSSL, wolfSSH, wolfMQTT, and wolfTPM all support being compiled on Yocto Project or OpenEmbedded based projects?  We recently refreshed our layer and recipe files to support the most current product versions, examples, and Open Source project bbappend files.

There are a several ways that projects can include wolfSSL products, or the wolfSSL embedded SSL/TLS library in Yocto Project / OE images.  wolfSSL maintains a layer called “meta-wolfssl“, located on GitHub here:


This layer includes recipes for:

  • wolfSSL embedded SSL/TLS library
  • wolfSSH lightweight SSH library
  • wolfMQTT lightweight MQTT Client Library
  • wolfTPM TPM 2.0 Library
  • wolfCrypt test application
  • wolfCrypt benchmark application
  • cURL .bbappend file, for compiling cURL with wolfSSL support

If you are interested in trying these recipes out, we have a great Getting Started document available here:

The wolfSSL product recipe is also part of the “meta-openembedded/meta-networking/recipes-connectivity” layer, located here:
