Use SHA-2 by default instead of MD5 for password encrypting

Let's face it: MD5, while it might be more than plain old DES, it is a weak algorithm to encrypt your passwords with. To give you proof, in 2008, researchers demonstrated that MD5 is very weak to collision attacks, and can create false data that appears to be trustworthy. For proof: http://www.kb.
