Vigenere Cryptosystem

Posted in Cryptography by

Vigenere is a poly alphabetic Cryptosystem, it changes the representation of the vocabulary in order to be less vulnerable to security attacks.

Vigenere uses a fixed length secret key and it splits the public key in parts of the length of the secret key. The public text and the secret key are converted to its numeric equivalents. Each part of the public text is shifted with the secret key.
