Heidi has a writing assignment to connect the code book to her own life. which line from her assignment best demonstrates heidi’s connection with the text? one interesting fact i learned in my reading is that the u.s. uses encryption to catch criminals. a central idea found in the code book is the fact that much of the world’s information is unprotected. the author shares several examples of codebreaking techniques, including trojan horses and viruses. after reading the code book, i will be more careful about the information i share online.
