Question :

Prepare a multithreaded code breaking program. You have been provided 3 files that contain text that have been encrypted using a Caeser cypher scheme.

The task is to figure out the 2 keys used in the scheme. The encryption algorithm looks like:

character = character + key1;

character = character ^ key2; (^ = xor) and encrypts the characters 1 by 1.

Your code requires to decrypt the 3 text files by guessing the 2 keys. You will know you have found the correct keys when you find in the text the string "Dr-Ronald-Marsh".

To get you started, the file HW10-A.dat uses the keys (1, 6) and the file HW10-B.dat uses the keys (25, 44). The file HW10-C uses keys > 0 && < 100.
