  Well, it's trivially defeated by lots of easily downloadable software, so
it's the kind of level of protection that would stop anyone casually browsing
through your file but wouldn't stop anyone who actually wanted to read it.

  gpg seems like a good choice, since it's open source and there's a cygwin
port.  Proper crypto done right.  Choose a nice long high-entropy passphrase
for your keyfiles and it's as close to unbreakable as makes no odds.
