Ask HN: gui front-end for ssh-keygen app?

Are there any applications which provide a GUI interface automating the process of setting up SSH key access to a remote server? I wrote up a blog post about this [1], but then I realized that something like this probably already exists, and I just don't know about it. Anyone familiar with something like this?
