Comment 1 Alexander Köplinger [MSFT] 2017-04-04 13:12:18 UTC
Should be fixed by https://github.com/mono/mono/pull/4601, Martin could you please take a look?
Comment 2 Martin Baulig 2017-04-19 16:11:55 UTC
See my review on that PR - we need to replace Mono.Security.Protocol.Tls (which is the old legacy implementation) with System.Net.Security.SslStream.

It shouldn't be too difficult, though.  Just replace SslClientStream with SslStream and a few more things.
Comment 3 Martin Baulig 2017-04-19 16:16:55 UTC
Let me give this tool the love that it deserve :-)
