A private key has (to the best of our knowledge -- we don't know everything
about mathematics) a precise 1 to 1 correspondence with a public key, and a 1
to 1 correspondence from a public key to a private key.
But I can't imagine why you'd want to present a different certificate to the
client

What all features do DTLS support?
I am not able to find the information about this on OpenSSL.org
I was going thru the headers to check, i think it supports.
1. Packet sequencing.
2. Sure delivery by retransmitting if it didnt get ACK.
I guess there should be more, Can someone please pin point to

Well, think of the device as proxy which acts as the client to the server
and server to the client. Hence, the proxy is configured with the same
public-key and private key as that of the server so that it can act as the
server to the clients. But before it starts to do that, I want to make sure

When building with Visual Studio, you are better off using a perl
version itself compil
Thanks Ben, I will try this.

Ok, well assuming you're talking about C++ which is what I'm using, then to
create an RSA key pair you do:
// alice would do this
RSA *rsa = RSA_generate_key(bits, 65537, NULL, NULL);
// alice can then get the public part of the key and send to bob
const int max_hex_size = (bits / 4) + 1;

Yes thats what i need to do. If you can provide some example, that will
be great.

Well I implemented something very similar recently but using tcp rather than
udp. In my case, alice creates a public-private key pair and sends public
key to bob. Bob then encrypts randomly generated symmetric key (.e.g
blowish, dsa or aes etc.) with public key and sends the result to alice.

In my project, the keys and certificates are not stored as a file, but are
