I am a huge fan of RoyalTS and after v4 it does pretty much everything I wanted from it, with one single exception.
That is the creation of SSH keys. So I thought Id bring it forward as a feature request for the future.
Thank you very much.
I have puttygen configured as an external application. It isn't perfect, but it is easy enough to use.
If you were doing a lot I would use ssh-keygen that comes with Git for Windows and set it up as a command line task.
