InheritanceVigenere Inheritance Object

The Vigenère cipher is a method of encrypting alphabetic text by using a series of different Caesar ciphers based on the letters of a keyword. It is a simple form of polyalphabetic substitution.

See the wikipedia article about it : Vigenère cipher 

     import calista.hash.Vigenere ;
     trace( Vigenere.encrypt( "hello world" , calista" ) ; // jewtg potlo
     trace( Vigenere.decrypt( "jewtg potlo" , calista" ) ; // hello world
