Your job is to decrypt this intercepted message, CQNTNHRBDWMNACQNVJC, which is believed to reveal the location of an important item. Your hint is that it is encrypted using a Caesar cipher, but we do not know the key. However, you have intercepted another message that may provide some useful information. 1.Since we know that the recipient of a ciphertext message must know the encryption key to decode the message, we were looking for a second message containing the key to our ciphertext, and we may have found it. We intercepted the following encrypted message: NEXYIYECEHTIRISNEHPK. Via social engineering, we believe the message sender likes to use route ciphers in a five-row by four-column grid. Past efforts lead us to believe she prefers to encrypt the message by writing the plaintext down the columns from right to left, and then spiraling counterclockwise from the top-left corner. If the plaintext doesn't fill the grid, she often uses X and Y to fill in the spaces. Reverse her process to reveal the plaintext! 2. If you correctly decrypted the message from step 1, you now have the encryption key for the original ciphertext, CQNTNHRBDWMNACQNVJC. Use this key and your knowledge of Caesar ciphers to decrypt the first message and find the location of the secret object.
