'-dns': remove support for 'exclude-domains' argument (this was a new 2.6 option, with no backend support implemented yet on any platform, and it turns out that no platform supported it at all - so remove option again).Add warning to '-show-groups' that not all supported groups are listed (this is due the internal enumeration in OpenSSL being a bit weird, omitting X448 and X25519 curves).Add warning if p2p NCP client connects to a p2mp server - this is a combination that used to work without cipher negotiation (pre 2.6 on both ends), but would fail in non-obvious ways with 2.6 to 2.6.This was a somewhat obsolete feature anyway as it only worked with OpenSSL 1.x, which is end-of-support. This had to be removed because the original author did not agree to relicensing the code with the new linking exception added. Remove OpenSSL Engine method for loading a key.DCO: warn if DATA_V1 packets are sent by the other side - this a hard incompatibility between a 2.6.x client connecting to a 2.4.0-2.4.4 server, and the only fix is to use '-disable-dco'.Work around build fails caused by LibreSSL not longer having engine support.DCO on Linux: fix NULL-pointer crash if '-multihome' is used together with '-proto tcp'.Cleanup code to remove strlen() related warnings in buf_catrunc().Cleanup bits and pieces of documentation.On platforms where division by zero is fatal, this will cause an OpenVPN crash. CVE-2023-46849 OpenVPN versions between 2.6.0 and 2.6.6 incorrectly restore '-fragment' configuration in some circumstances, leading to a division by zero when '-fragment' is used.not using -secret) are affected by this issue.

Voor de beveiliging wordt gebruikgemaakt van de OpenSSL-library, waarmee alle encryptie, authenticatie en certificatie kunnen worden afgehandeld. OpenVPN is een robuuste en gemakkelijk in te stellen opensource-vpn-daemon waarmee verschillende private netwerken aan elkaar geknoopt kunnen worden via een versleutelde tunnel over internet.
