+# 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
+
+Calling ctx Init from wolfSSL
+Finished init of ctx .... now load in cert and key
+Ciphers : TLS13-AES128-GCM-SHA256:TLS13-AES256-GCM-SHA384:TLS13-CHACHA20-POLY1305-SHA256:DHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES256-SHA256:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-CHACHA20-POLY1305:DHE-RSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305-OLD:ECDHE-ECDSA-CHACHA20-POLY1305-OLD:DHE-RSA-CHACHA20-POLY1305-OLD
