Is it possible to use DTLS with some sort of non-socket BIO? Basically, I have datagrams which I know belong to a specific DTLS session, and I want to feed them to OpenSSL and get back further datagrams to send out in response. (This is similar to what SSLEngine does in OpenJDK, except there it's for plain TLS.) An example how to establish a DTLS session with multiple peers over an unconnected socket would help, too. -- Florian Weimer / Red Hat Product Security
