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) Upstream-Status: Backport [https://src.fedoraproject.org/rpms/openvpn/blob/rawhide/f/0001-Change-the-default-cipher-to-AES-256-GCM-for-server-.patch] Signed-off-by: Wang Mingyu <wangmy@fujitsu.com> --- .../recipes-support/openvpn/openvpn/openvpn@.service | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
