Utilize XML to store configuration settings

I use this XML serialization to store passwords, etc. as well. The .NET framework provides easy access to hashing and encryption methods to store a plain-text password in non-human-readable form.

Here's the tip: make a public variable to store the hash of the password instead of the password. Use your favorite functions to encrypt or hash... I like Joshi's code at

except I might add a "salt" to the password to make it less vulnerable to dictionary attacks. Of course if you require heavier security you might look into a stronger symmetric or asymmetric encryption technique. Check out

Just guessing, but listing D is deficient in space characters at "ReadOnlyfilepath".
Perhaps a context sensitive parser would DTRT but its ages since I was coding on a regular basis and maybe the world is a kinder place nowadays.
