This source code to create a vigenere cipher text and decript de text, also it has the kasiski method-This is source code to create a vigenere cipher text and decript de text, also it has the kasiski method

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.Though the cipher is easy to understand and implement, f
