is there a method to enable the use of dh key size 2048 for ssl connections?

[omerbrandis]

Hello all,

I've been using Poco::Net::HTTPServer with Poco::Net::ServerSocket successfully for a while,
and have lately been asked to enable use of dh key of 2048 in the ssl handshake.
I've noticed that there's a dedicated parameter for this in the Context class called dhUse2048Bits
but also that SSLManager::initDefaultContext does not explicitly set it, and in practice it looks like that the ssl handshakes are made using a 1024 bit key. ( the cmd openssl s_client -connect .... returns "Server Temp Key: DH, 1024 bits").

thus I'm my question is how can the use of dh key sized 2048 can be enabled ?
or if there's a workaround for this ?

thanks
