George’s company follows a strict confidentiality policy when it comes to the exchange of information. To prevent the leakage of information during transmission George also informed his employees during the meeting that he will be sending them instructions encrypted under Caesar cipher followed by another substitution where the key is 234. Employees received the following cipher text. NTJWKHXK AMK WWUJJYZTX MWKXZKUHE What is the plain text?

Explanation / Answer

Answer)

Cipher text is the end product of an encryption made to a plain text using the algorithm called Cipher.

This kind of encryption and decryption process is much needed to send confidential information without the knowledge of the users/hackers.

The exchange of information for a highly confidential data's use this technique to transfer the data's.

The plain text for the below encrypted text using key 13 is:

NTJWKHXK AMK WWUJJYZTX MWKXZKUHE

Decrypted Text: AGWJXUKX NZX JJHWWLMGK ZJXKMXHUR

Cipher text is the encrypted information as it contains the original plain text which is unreadable by a human or computer without a proper cipher to decrypt it.

Note: The key 13 used is the ROT13 (rotate by 13 places) key which is used to replace a letter with the 13th letter after it (As we have 26 alphabets in English language, the half being 13 is being used to reverse the string to decrypt).
