I decided to start moving some old code of mine onto GitHub. This might be useful for some people managing large numbers of servers via Windows. I don't know of any software (other than Puppet although its different) for doing this.
Just a simple little program that makes it easy to setup key based authentication on your Linux server. Don't blame me if your computer spontaneously explodes or far more likely you lock yourself out of your server. No warranty implied.
You can also drag multiple putty shortcuts where the username and host are given in user@hostname format onto the window and it will process them with the given values (password & key) automatically.

Not very pretty code, I am sorry. Feel free to fork and take over. If anyone knows of open source software that does this let me know, this is still the solution I use.
