        public void init​(java.lang.String pwdPath)
                  throws java.io.IOException
        Initialization method to read passwords(key and element pairs) from a file.

        Every property occupies one line of the input stream. Each line is terminated by a line terminator ( \n or \r or \r\n). Lines are processed until end of file is reached.

        A line that contains only whitespace or whose first non-whitespace character is an ASCII # is ignored (thus, # indicates comment line).

        Every line other than a blank line or a comment line describes one property to be added to the table. The characters before the delimiter = forms the key and the characters after the = is assigned as value to the key.

        As an example, each of the following lines specify the key "Truth" and the associated element value "Beauty":

         Truth = Beauty
         Truth= Beauty
         Truth                    =Beauty
         

        Note that the space appearing before/after = is ignored. However, the space appearing in between are stored.

        Example:

         Welcome Message  = Hello World
         
        assigns value Hello World to key Welcome Message

        If the line doesn't have the delimiter =, the method throws an IOException
