The System.Web.Security.FormsAuthentication.HashPasswo rdForStoringInConfigFile method generates a hash in a couple different formats that you can use as your stored value. Even though it's in the web namespace you can still reference that from a windows form.

This hash method is a one-way encryption. Store the hash result in the database. Then when you need to check the password, use the same method to hash what the user enters and compare the two hashed values. The only real side effect is that you can never retrieve the plain text password.
