Alice and Bob are two fugitives from justice. Alice sent Bob an
encrypted message to inform him about her following secret meeting
location. As a cryptanalyst, it is your mission to help the police in
decoding the message that contains the room number and the hotel
name.
Alice’s SECRET MESSAGE IS: 7F7F Norzut jkgjykg
Use Cryptool to decrypt the secret message using Caesar cipher.
Assume the following:
