I've (finally) successfully got 
System.Configuration.Configuration.ConfigurationSection.SectionInformation.ProtectSection
working to en/de-crypt an XML config file.
But I just read that both RsaProtectedConfigurationProvider and DataProtectionConfigurationProvider will only work on one given computer, which makes sense now that I think about it.
What is the easiest way to enable users to share an encrypted XML config file and allow them to all open it. I read about rolling my own encryption but is there any easier way?
