This is a simple example of a TCP server and client both wrapped with a SSLStream with a self-signed certificate. Companies usually buy a certified certificates but this can be unnecessarily for small projects. If you use a self-signed certificate instead as in this case you will only be left with the encryption part of SSLStream. By using the native C# SSLStream library you don't need to implement your own network encryption method with, say, RSA + AES. Although you won't get the authorization part of SSL, the stream will still be encrypted.
- The code is written in C#.
Guide to set up:
- Create two executable projects using the code found in "SSLClient.cs" and "SSLServer.cs".
- The SSLServer needs a certification file. You can either use the one found on this repository or you can create your own.
- Place the certification file in the same folder as the SSLServer executable before starting the server. After the server is running, start the client.
Guide to creating your own self-signed certificate on Windows:
- Find the "makecert.exe" and "pvk2pfx.exe" files by navigating to "C:\Program Files (x86)\Windows Kits\8.0\bin\x64". If you cannot find the folder you need to install the "Microsoft Windows SDK" found Here.
- Navigate to the folder with the terminal. You can start the terminal in a folder by right-clicking and choosing "Open command window here".
- Run the following two commands to create a certification file named "server.pfx":
"makecert.exe -r -pe -n "CN=localhost" -sky exchange -sv server.pkv server.cer"
pvk2pfx -pvk server.pkv -spc server.cer -pfx server.pfx -pi password
"password" can be replaced by whatever you entered when you ran "makecert.exe". I choose "password" everywhere.
