tls: use default OpenSSL built-in DH parameters
Type: improvement Motivation for this addition is to add support for cipher suites that use Diffie-Hellman Ephemeral (DHE) for key exchange. Using ephemeral DH key exchange yields forward secrecy as the connection can only be decrypted when the DH key is known. Configure OpenSSL to use the default built-in DH parameters for the SSL_CTX object. Change-Id: I31aadad047a6394ddf8bfa08471c239e0d1cd63c Signed-off-by: Ofer Heifetz <oferh@marvell.com>
