According to https://stribika.github.io/2015/01/04/secure-secure-shell.html, curve25519 and ed25519 are the methods of choice for DH exchange and pubkey authentication, respectively.
Unlike some other elliptic curve stuff, they are represented as patent free by the author. Refer to http://ed25519.cr.yp.to/ for further details.
I think WinSCP should support these as soon as possible.

WinSCP uses an SSH implementation from a PuTTY project. Consider contacting PuTTY team with your request
http://www.chiark.greenend.org.uk/~sgtatham/putty/feedback.html

We will takeover their implementation, if they decide to support it.

Thanks.

Hello folks,

I found this post about ed25519 here: https://winscp.net/forum/viewtopic.php?t=14731
PuTTY has added support for ed25519 and ecdsa in it's snapshot channel. Is it possible to get a build of WinSCP with this support?
I had a look at it myself but the changes to the dev build over the current codebase in WinSCP are more than I anticipated.

Thanks

We do not plan to upgrade to dev code of PuTTY. We typically wait for an official release.

Is it possible to do a dev code release? I have no worries with compiling WinSCP, but I use ed25519 keys and WinSCP not being able to take them is frustrating. The intergration of PuTTY into WinSCP is a little out of my skillset.

We will consider it.

Hello!
PuTTY was released 0.65 some time ago. Do you plan to make support of ed25519 keys and other modern cryptographic methods? For now isn't possible to connect to some servers from WinSCP and Netbox (Far Manager plugin https://github.com/michaellukashov/Far-NetBox/)

But Ed25519 is not in PuTTY 0.65.
