Storing SSH Password encrypted...

Question

I am writing a very small application for our tech support guys to be able to reboot some of our routers remotely.  Because of security concerns, these tech support guys cannot have the password to login to the router - so I have the task of writing a small application that connects to the router via SSH, and sends a reset command.

I have this part working up until now - the username and password for the router is hard coded into the application.  I am looking to store this information somewhere external to the application, in some sort of encrypted format because this password must change every 90 days.

What is the best way to do this?  I looked into MD5 hashing, but that is only a 1 way hash and I don't think that will work for what I am trying to accomplish.

Thanks in advanc efor any input.
