Ignore my previous remark. I forgot that, if you want to use Ed25519
keys via ssh-agent or Pageant with the current version of TurboVNC, you
have to add
PubKeyAcceptedAlgorithms +ssh-ed25519
to ~/.ssh/config (%USERPROFILE%\.ssh\config on Windows.)
That is because the SSH client doesn't explicitly support the signature
scheme, so you have to tell it that it is OK to use that scheme (which
it is, because the SSH agent supports it.)
I am still working on explicit Ed25519 support, which will make it
unnecessary to modify the OpenSSH config file.

I reproduced the issue, and it is definitely due to the use of an
Ed25519 key. I guess ssh-agent communicates the key in such a way
that the key type doesn't matter, but it does matter with Pageant.
Ed25519 support is a high priority for TurboVNC 3.2.

Hi. Pageant version is 0.81 and I generated the key using ssh-keygen
(Windows 11 WSL2 - Ubuntu 22.04 - openssh-client
1:8.9p1-3ubuntu0.10). The key type is actually Ed25519. I will change
the key type or wait for the TurboVNC 3.2. Thanks for the detailed reply.

OK, that sounds like a bug, then. Which version of Pageant are
you using? How did you generate the key? (I ask the latter
question because there are still some key algorithms that the
TurboVNC Viewer’s built-in SSH client doesn’t support—
specifically Ed25519. I intend to address that in TurboVNC 3.2.)

I've loaded the .ppk file to Pageant and the SSH connection
works with Putty and Windows OpenSSH but I get the password
inquiry in TurboVNC (without any TurboVNC parameters).

The SSHKeyFile parameter accepts an SSH key in OpenSSH
format. It is roughly the equivalent of the -i option in
OpenSSH. In other words, it is a command-line override that
allows you to promote an SSH key to the top of the chain. It
isn’t necessary when using an SSH agent. You should be able
to simply add the .ppk file to Pageant, and the TurboVNC
Viewer will use the key through Pageant automatically. No
further TurboVNC parameters or OpenSSH config file
directives are necessary.

Hi,
I'm not able to use Pageant with .ppk-file for SSH login.
I've included the Pageant 'IdentityAgent- in the '
C:/Users/username/.ssh/config'. Pageant works fine with
Windows OpenSSH.
I use the option
"sshKeyFile=C:/Users/username/.ssh/private_key.ppk" with
TurboVNC viewer version 3.1.2 but I get an error: "Could
not create SSH tunnel: Could not use SSH private key
C:\Users\username\.ssh\private_key.ppk: invalid privatekey:
[something" with 'something' being some hash.
Great software nevertheless.
