MD5 is a hash algorithm, which means it's a one-way encryption. You  
have no way of decrypting the hash to the original password. And since  
you are using a salt, even the rainbow tables hackers use will be  
pretty useless.

If your app isn't in  production yet, you could consider a decryptable  
algorithm, like the ones you can find in Sentry: http://sentry.rubyforge.org/
