How does openvpn do symmetric key management?We want to know specifically as to how to change the symmetric key periodically. Also does openvpn support both manual and automatic key management?
Symmetric keys must be pre-shared via a pre-existing secure channel. OpenVPN doesn't manage them.
Most people use TLS mode rather than static key mode (using symmetric keys) because it handles cipher/MAC key management and renegotiation automatically.
