This code takes letters, encrypts each letter into 2 numbers (a=01, b=02), then changes a cloud variable to the set of numbers. The cloud variable then comes to your computer, decrypts the length of numbers, then shows you the result. A piece of code checks if the cloud variable has changed, then decrypts the cloud variable if it's changed. Doesn't support Caps, but can use them.
