# 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 (Ubuntu) using mono

Prerequisites for linux:

```
apt-get update
apt-get upgrade
apt-get install mono-complete
```

# Build wolfSSL and install

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

# Build and run the wrapper

```
cd wrapper/CSharp

msc wolfSSL_CSharp/wolfSSL.cs wolfSSL_CSharp/X509.cs \
    wolfSSL-TLS-Server/wolfSSL-TLS-Server.cs
```

# Run the example

```
cp wolfSSL_CSharp/wolfSSL.exe ../../certs
cd ../../certs
mono wolfSSL.exe
