Select OSS Projects Using wolfSSL Products

A number of popular open source and community projects use wolfSSL products, or can be alternatively compiled with wolfSSL support instead of the default SSL/TLS provider.  When porting the wolfSSL lightweight SSL/TLS library into an existing Open Source project, wolfSSL tries to upstream changes/patches. This is not always possible, and as such we maintain this repository of patches and modified projects in the following GitHub repository:

wolfSSL Open Source Project Ports:

A list of open source and community projects that use wolfSSL products is below:

MySQLThe world’s most popular open-source database.

BMX6BMX6 is a pro-active, loop-free, distant-vector protocol for IP-based ad-hoc networks combining general concepts of destination-sequenced distant vector protocols with a new node-referencing scheme for referring and identifying nodes.
CURLCURL is a popular command line tool for transferring data with URL syntax, now with a build option to use wolfSSL for TLS.
mongooseMongoose is an easy to use web server that can be used as an embedded web server library to provide interfaces to applications.
libscsSCS is a small cryptographic protocol layered on top of the HTTP cookie facility [RFC6265], that allows its users to produce and consume authenticated and encrypted cookies, as opposed to usual cookies, which are un-authenticated and sent in clear text.
TinyPKCA port of the wolfSSL/wolfCrypt implementation of RSA and ECC to TinyOS 2.x. It is released under the GPLv2 license.
GearmanGearman provides a generic application framework to farm out work to other machines or processes that are better suited to do the work. It allows you to do work in parallel, to load balance processing, and to call functions between languages.
fb4ndsSimple Nintendo DS client for Facebook's chat. The project is compiled with devkitARM and uses libraries including PAlib, libNDS, libdswifi, libgif, libctaocrypt, libcyassl, libz and libpng.
openGalaxyopenGalaxy aims to provide a method for listening on a serial port and decode incoming messages from a Galaxy security control panel. The messages are transmitted using the SIA DC-03-1990.01 (R2000.11) protocol. The decoded messages are stored in a database (MySQL) or forwarded by email using ssmtp.

OpenSSHThe leading tool for remote login with the SSH protocol to keep your communiqués secret.

Porting into Existing Projects

We are actively recruiting community members who are interested in porting OpenSSL-based projects to wolfSSL either using our OpenSSL compatibility layer or native wolfSSL API. Through the process of completing additional OpenSSL to wolfSSL ports, we can incrementally improve the compatibility layer for all.

To contact us regarding any community related issues, email us at If you’re working on a port, please let us know!  We’d love to hear about it!


SWIG - an interface compiler that connects programs written in C and C++ with scripting languages such as Perl, Python, Ruby, and Tcl. It works by taking the declarations found in C/C++ header files and using them to generate the wrapper code that scripting languages need to access the underlying C/C++ code. In addition, SWIG provides a variety of customization features that let you tailor the wrapping process to suit your application.
