The story follows Susan Neveu, a young and talented cryptanalyst at the National Security Agency (NSA), and John Clay, a computer expert who becomes embroiled in a mystery surrounding a powerful computer system called "Digital Fortress". The system, created by the enigmatic and reclusive programmer Ensei Tankado, has the capability to encrypt and decrypt any piece of information, making it virtually unbreakable. When Tankado dies suddenly, he leaves behind a cryptic poem that leads Susan and John on a thrilling quest to unravel the secrets of Digital Fortress.

Of course, the novel’s technological plot is famously absurd. Brown’s description of a brute-force decryption machine is pure Hollywood, and the idea of a "passkey" that is also a fatal virus is cryptographic nonsense. But the social fear is prescient.
