In a recent blog post, security expert Bruce Schneier recounts the story of Harvest, a specialized code-breaking computer built by IBM for the NSA in the 1960s. The machine was not a general-purpose computer but rather a dedicated tool designed for cryptanalysis, reflecting an early investment in hardware tailored to a single, high-stakes task.
Schneier's retelling underscores how the practice of building custom machines for breaking codes is far older than modern debates about encryption backdoors or quantum computing. Harvest stands as a historical reminder that governments have long sought technological advantages in surveillance and intelligence, often commissioning bespoke hardware to achieve them.
Because this article relies on a single source—Schneier's blog—there are no differing accounts to note. His narrative offers a concise, anecdotal glimpse into a lesser-known chapter of computing history, framed within the broader context of security and privacy concerns that remain relevant today.
