Actually, there is more than one key that is derived from the pre-master key. There is both an encryption and HMAC keys for both transmission and reception. That translates to 4 separate keys. Bob From: owner-openssl-us...@openssl.org [mailto:owner-openssl-us...@openssl.org] On Behalf Of Aravinda babu Sent: Saturday, April 03, 2010 6:39 AM To: openssl-users@openssl.org Cc: openssl-...@openssl.org Subject: Pre Master Secret Regarding Hi all, During SSL/TLS handshake,a pre master secret is sent from client to the server by encrypting pre master secret with server's public key.From that both client and server derive master secret and finally one symmetric key.My doubt is, why both cannot use pre master secret itself as a symmetric key ? Thanks in advance, Aravind.
