I am having difficulty creating a new keypair using ssh-keygen.exe and a passphrase - should this be working? I receive the error ``Saving key "[...]/.ssh/id_ed25519" failed: invalid argument''.
It works fine without a passphrase.
Haven't seen that error message before but I highly encourage you to use our GitHub builds where we've fixed a ton of issues related to path parsing and VT100/ANSI compatibility.
Those builds will also be showing up in Insider builds over the next few weeks (if they haven't already).
I had the same issue, plus -t rsa didn't work, and my existing keys weren't accepted anymore. I ended up uninstalling it.
As part of the beta, we only support crypto algorithms that ship as part of OpenSSH itself, as opposed to algorithms that ship in OpenSSL/LibreSSL. Hence, we only support ed25519 in Fall Creators Update.
If you grab our GitHub bits, we compile against LibreSSL there, and you should see LibreSSL showing up in future Insider builds of Windows. That brings support for all the other crypto algorithms you'd expect (RSA, DSA, etc.)
