Hello, I have a cipher suit : TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA What is It meant TLS_DHE_RSA Combine between RSA with Diffie-Hellman ?? RSA is key transport. DH is key agreement. How do they use together ?? Please help. When we use Ephemeral DH, we need to use a (RSA or

Hi All I have a hard time to understand Diffie-Hellia Key agreement. This is a DH structure Typedef structure dh_st { BEGIUM *p; BEGIUM *q; BEGIUM *pub_key; BEGIUM *priv_key; } According to Openssl Book p and q, each pair chooses a random large integer priv_key member. A value for
