In OpenVPN which algorithm is used for control channel encryption (
--tls-crypt directive in OVPN profile)?
--tls-crypt, will there be only encryption or authentication-then-encryption? I want to disable
--auth by using
alg=none parameter. I know
--auth is required for
--tls-auth (control channel authentication).
--auth necessary for
--tls-crypt too, or I can disable
--auth without any upcoming issues related to
Update 1: I searched in OpenVPN 2.4 manual and it states --tls-crypt is used for encryption "and" authentication control channel. The rest of the question remains unanswered.
Update 2: After searching in OpenVPN support forum; I realized --tls-crypt uses AES-256-CTR for encryption; still know nothing about the authentication side.
