Support for v3 Putty Key Files

Question

Apologies if this has been asked, but I don't find the search very helpful at all.

EnterpriseDT.Net.Ftp.Ssh.SFTPException: 'Failed to recognize key format.  Supported formats are OpenSSH, SSH.com and PuTTY.'

The problem? I'm trying to use an OpenSSH key which was automatically converted to a PuTTY key by FileZilla.  It seems to be a PuTTY v3 key, and the product only supports v2.

PuTTY-User-Key-File-3: ssh-rsa

So now I'm using the OpenSSH key for my .NET code and the FileZilla-converted key for FZ. I'd like to be able to use the same key for both. Any plans to support v3 of PuTTY keys?

Answer 1

PuTTY v3 private keys have been supported since 11.0.0. A bug was fixed in 12.0.0 for unencrypted keys.

So you mean I shouldn't be using version 10.1 from 2023, and I need to do more than run the installer for 12.5, I actually need to copy the dll and use it in my directory tree?

Move along - nothing to see here!

Yes, you always need to ensure the DLL referenced in your project is the one you want. 10.1 does not support PuTTY v3 private keys.
