PuTTY & PPK Private Keys

[SJLennon]

The Login Setting dialog says that PPK formats are supported:

I believe that by PPK keys mean keys generated with PuTTYgen. I have found that such keys won't connect with Code4i in a Windows 11 environment, though they do connect with PuTTY. So perhaps this dialog should be changed.
My PuTTY and PuTTYgen are version .073.

I also believe that PPK keys once did work with Code4i.
Not supporting PPK private keys is not a major impediment. If you have a private/public key set created with PuTTYgen, you can load the private key with PuTTYgen and save it in another format, e.g. RSA or Ed25519 and this key will connect using the public key that you generated with PuTTYgen.
