DTLS.Net - C# Library that implements DTLS protocol

---

DTLS.Net

DTLS.Net was developed for use in an implementation of the Open Mobile Alliance's (OMA) Lightweight Machine to Machine protocol (LWM2M). For this reason it only supports the following cipher suites:

• TLS_ECDHE_ECDSA_WITH_AES_128_CCM_8
• TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256
• TLS_ECDHE_PSK_WITH_AES_128_CBC_SHA256
• TLS_PSK_WITH_AES_128_CCM_8
• TLS_PSK_WITH_AES_128_CBC_SHA256

Limitations

Since the client is only required to serve for the above project it has several inherent limitations:

1. No automatic retransmission
2. No support for fragmentation of handshake packets
3. Does not verify Server Certificates (against CA)

The server currently also has the following limitations:

1. Does not verify client Certificates
2. No support for fragmentation of handshake packets

Hopefully over time these will be implemented, in the meantime we hope this is still useful.

dtls.net's Issues

Import Cert from Windows Store

I'm looking at the TestClient project and it's pretty similar to what i need, except instead of loading a pem file, I'm looking at loading a certificate from the Windows Certificate store. I know how to get the cert from the store, the problem I'm having is getting it loaded into the Client. Is there something existing that I'm just missing? Or if not, any tips on how I could add something?

Upgrade to VS Code 2017?

To open this project in Visual Studio 2017, I had to perform a migration.
The auto migration went well, and made some changes to the code. Is there interest in a pull request with these changes?
