WebJun 14, 2015 · The private key is only used to sign the DH handshake, which does not reveal the pre- master key. Diffie-Hellman ensures that the pre-master keys never leave the client and the server, and cannot be intercepted by a MITM. All versions of nginx as of 1.4.4 rely on OpenSSL for input parameters to Diffie-Hellman (DH). WebDiffie-Hellman enables parties at both ends to derive a shared, secret key from a common starting point without the key ever being transmitted from one side to the other.
