Encoding a password

No problem. It's a misconception of a lot of programmers that are self taught that you need to decode a password to authenticate a user. You need to find the method which takes the most processing power to hash and then you hash a user input and compare the final result.

The longer it takes to process a hash, the harder it is for someone to replicate it using brute force. It increases exponentially.
