An Introduction To Cryptography
Cryptography is the stuff of spy novels and action comics. Kids once saved up
bubble-gum wrappers and sent away for Captain Midnight’s Secret Decoder
Ring. Almost everyone has seen a television show or movie involving a
nondescript suit-clad gentleman with a briefcase handcuffed to his wrist. The
word “espionage” conjures images of James Bond, car chases, and flying
bullets.
