Hello everybody.

I'm currently evaluating which ciphers and encryption methods are supported by softether, especially when using openvpn client to connect and it looks like, that the website might not be 100% up to date anymore.
I was wondering, if elliptic curve cryptographie (e.g. ECDHE) is already supported? Also i was wondering if CBC mode (cipher block chaining) or XDS is supported?

Thanks in advance and best regards,
Julian

Hi solo,

Thanks for your fast reply.

So if i saw that right, the above mentioned ciphers are not yet integrated/usable or am i missing something?

I am also curious if the ciphers added in Version SoftEther VPN 4.22 Build 9634 Beta (November 27, 2016) (https://www.softether.org/5-download/history) are supported?

Thanks!

Best, Florian

Thanks again!

Thats great, I've just seen this is already included in the stable version binary. The only question left for me now is, how can I force the connection to use e.g. ECDHE resp. where I need to configure this?
