$2\mathrm{.}5.$ Use the circuit and its truth table as a cryptography cypher. You have to encrypt the number from $2\mathrm{.}3.$ to send it securely to your friend. Use a repetition of the number from $2\mathrm{.}4.$ as an encryption key. Determine the encrypted number using the circuit function applied bit$-$by$-$bit $(0\mathrm{.}5$p$)$
