password encoder

    /*
    - Password Encoder
    - Encodes a password so it cannot be converted back into plain text by anyone
      that has access to the database.

    $password     - The plain text password that was entered by the user for encoding
    $salt         - Optional but recommended, "salts" the password to make it even harder
                    to be decoded. Can be generated with the function generateSalt()
    $hashType     - Default is sha512, the hashing algorithm to use between:
                    sha1, sha256, sha512, ripemd160
