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

DTLS2.Net was developed for use with Net-SNMP and an RSA certificate from the Windows Certificate Store and adds a new CipherSuite on the client side

• TLS_RSA_WITH_AES_256_CBC_SHA

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

1. No automatic retransmission
2. No reordering of messages or fragments
3. Does not verify Server Certificates (against CA)
4. No resumption when using the New Session Ticket Extention

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.
