Yes, DHE has dropped because it is hard to get right, and it takes more CPU 
cycles than ECDHE.



DH group cipher suites getting rejected

2019-09-18 Thread Chitrang Srivastava
Hi,

Why google rejected DH ciphers suites, I am trying
*openssl s_client -cipher 'DHE-RSA-AES128-GCM-SHA256' -connect
www.google.com:443 *
However if I try ECDHE, it works fine. Is DHE only cipher suites less
common now ?
I believe its responsibility of server to generate DHparam of large enough
size.

Thanks
