Encrypt "CORONA VIRUS" using Vigenère cipher with key "VACCINE".

The message 123 001 324 219 139 has been encrypted with an RSA Public Key Encryption scheme with encryption key (391, 35). Decrypt the message..

Use the modified Caesar cipher described in the assignment instructions to decrypt the following:Ciphertext:  UCTOTBWVUCKey: 5

Encrypt the following ciphertext "KLE" using Caesar cipher.

q11-  "Moral" has been encrypted with Caesar cipher to "Rtwfq". Find the key to this Caesar cipher?  Hint:  Convert the numbers into mod 26 range.  (0,1,2,3,.... 25)   a- 31 mod 26 b- 34 mod 26 c- 26 mod 26 d- None

Encrypt the message "DISCRETE MATHEMATICS" using the shift cipher with k=7

Encode the bold message using a one-time pad. Then reverse the process to decode the encrypted message. You may perform the calculations manually or automate by writing a computer program. Show the details of all steps in the process. MATH 221 covers the basics of Cryptography!
