The wolfSSL embedded SSL/TLS library supports features not only pertaining to TLS, but DTLS as well! A prime example of a DTLS feature supported by wolfSSL is DTLS session exporting. This allows for serializing and sending a DTLS session immediately after the handshake has been completed. The ability to export the session after a handshake is established has many practical use cases in IoT and embedded environments.
In establishing and maintaining a DTLS connection the handshake portion is the most resource intensive. With this additional feature it is possible to offload the handshake onto a more powerful system, serialize and export it after the handshake is completed, and then have throughput handled by a more resource constrained device.

wolfSSL also supports TLS 1.3! More information can be found here: https://www.wolfssl.com/docs/tls13/
