encryptedKey = "ESCPPP" This key was encrypted using a Caesar Shift Cipher, an encryption method used by Roman emperor Julius Caesar to encrypt military messages. The key to decrypt this message is 7.

You have found one piece of of the lost roman sundial:

String Manipulation

string = "abcdef"

LENGTH(string) would return the number of characters in the string (e.g. 6)

LEFT(string,3) would return the first 3 characters of the string (e.g. "abc")

RIGHT(string,3) would return the last 3 characters of the string (e.g. "def")

MOD & DIV

DIV is the quotient of a division, whereas MOD is the remainder.

For instance: 20 / 3 = 6 remainder 2

So:

20 DIV 3 would return 6

20 MOD 3 would return 2
