Adding wolfSSL (formerly CyaSSL) support
In order to support SSL HTTPS connections in Civetweb,
you may wish to use the GPLv2 licensed CyaSSL library. By using this
library, the resulting binary may have to have the GPL license unless
you buy a commercial license from wolfSSL.
Note: The following instructions have not been checked for the most recent versions of CivetWeb and wolfSSL. Some information might be outdated. All current versions of CivetWeb are tested using OpenSSL. CivetWeb uses the OpenSSL API functions - wolfSSL
provides an OpenSSL compatibility layer. However, when new TLS features are added to CivetWeb, it is not checked if corresponding functions work the same, or even if they exist at all within this compatibility layer.
Getting Started
Example Project
If you download cyaSSL to cyassl-2.7.0 in a directory parallel to Civetweb, you can open the VS/civetweb_yassl solution in Visual Studio.
