wolfSSL CSharp Wrappers

This directory contains the CSharp wrapper for the wolfSSL TLS layer with examples.

• wolfSSL_CSharp: wolfSSL TLS layer wrappers (library)

Examples:

• wolfSSL-DTLS-PSK-Server
• wolfSSL-DTLS-Server
• wolfSSL-Example-IOCallbacks
• wolfSSL-TLS-Client
• wolfSSL-TLS-PSK-Client
• wolfSSL-TLS-PSK-Server
• wolfSSL-TLS-Server
• wolfSSL-TLS-ServerThreaded

Windows

A Visual Studio solution wolfSSL_CSharp.sln is provided. This will allow you to build the wrapper library and examples. It includes the wolfSSL Visual Studio project directly.

Linux (using Mono)

Prerequisites for linux:

apt install mono-tools-devel

Build wolfSSL and install:

./autogen.sh
./configure --enable-wolftpm
make
make check
sudo make install

Build and run the wrapper:

cd wrapper/CSharp

csc wolfSSL_CSharp/wolfSSL.cs wolfSSL_CSharp/X509.cs \
    wolfSSL-TLS-Server/wolfSSL-TLS-Server.cs

Run the example:

cp wolfSSL-TLS-Server.exe ../../certs cd ../../certs

mono wolfSSL-TLS-Server.exe
