How to decrypt the cipher encrypted by the algorithm showed as below when clearText and key are not given:

def encrypt(cleartext, key):

to_return = bytearray(len(cleartext))

for i in xrange(len(cleartext)):

to_return[i] = ord(cleartext[i]) ^ ord(key[i % len(key)])

return str(to_return)

1 Introduction A cipher is an algorithm which encrypts a message into cipher text so that it can be safely transmitted without an eavesdropper being able to (easily) read it. For the purposes of this assignment the message and ciphertext will be stored as strings of ASCII characters. Cipher algorithms always perform two tasks: encryption and decryption. The encryption process takes a “message” and “key” as inputs and produces cipher text. The decryption process performs the reverse: it turns cipher...

The Vigenère Cipher is an encryption algorithm that combines the use of a keyword with the message to be encrypted. A tableau is provided that shows an encrypted character for each combination of characters in the message and the keyword. Using the Vigenère Tableau encryption scheme with a keyword of KEYWORD, encrypt the following message: IS INFORMATION SECURITY ESSENTIAL After encrypting the message, decrypt the following message, using KEYWORD as the keyword: YRJUW WWRIG JTFUW ERECE LCMKL CIWKR R For...
