1) Implement Cesare Cipher Algorithm using C++ or Java. The program:
1.1. Should prompt the user to enter “E” for encryption or “D” for decryption.
1.2. Prompt the user to enter an encryption key when “E” is chosen
1.3. Prompt the user to enter the decryption key when “D” is chosen
1.4. Should be able to take the plain text from a notepad file stored in a hard disk as
CeaserPlain.txt.
1.5. Encrypt the input file up on the reception of the key and store the cipher text as
CeaserCipher.txt
1.6. Decrypt the cipher text up on the reception of the decryption key and store the plain
text as CeaserPlain2.txt. creaser Cipher should be read from hard disk.
1.7. Generate an error message when encryption and decryption keys do not match.
