Subject: [PATCH] Change the default cipher to AES-256-GCM for server
configurations
This change makes the server use AES-256-GCM instead of BF-CBC as the default
cipher for the VPN tunnel. To avoid breaking existing running configurations
defaulting to BF-CBC, the Negotiable Crypto Parameters (NCP) list contains
the BF-CBC in addition to AES-CBC. This makes it possible to migrate
existing older client configurations one-by-one to use at least AES-CBC unless
the client is updated to v2.4 (which defaults to upgrade to AES-GCM automatically)
