[Mediawiki-l] encrypt mySQL password?

[dug]

I've noticed that the admin password to the mySQL db is included in plain 
text in the LocalSettings.php file in my Wiki directory, which is set to 
755, readable and executable by the world. Am I being paranoid, or is this a 
slightly insecure situation?

Can the password be encrypted, or is there some other security measure I 
should take?

TIA
