WebYou can generate a new dhparams with openssl: openssl dhparam -out dhparam.pem 2048 Then configure your server that is using the dhparams to use the new file, and restart. We did this a long time ago with nginx and apache. There is generally a dhparam file that is used for the system centrally located in /etc for RHEL/CentOS. WebThe Diffie–Hellman key exchange takes place in the subgroup G of order q. Computation of H 1 then involves an exponentiation with exponent r in order to move a bitstring into the subgroup G. Since the typical lengths of q and r could be 256 bits and 1792 bits, respectively, this calculation is more expensive than the WebI type the following command to get the server info: openssl s_client -connect 10.7.5.65:9443 -msg.
