Auguste Kerckhoffs
Jean Guillaume Auguste Victor François Hubert Kerckhoffs was a Dutch linguist and educator whose work became a lasting foundation of cryptographic engineering. In 1883 he published La Cryptographie Militaire, a two-part discussion of practical military-cipher design.
Security by design
Its best-known rule holds that compromise of a system’s mechanism should not compromise the communication: protection should reside in the key. The idea is often called Kerckhoffs’s principle and is commonly contrasted with security through obscurity.
Why he belongs here
Kerckhoffs framed security as an engineering problem involving exposure, usability, key management, and operational constraints. Those concerns remain recognizable in contemporary security design.
In memoriam
Kerckhoffs died in Paris in 1903. His 1883 essay continues to be cited as a foundational statement of how secure systems should be designed.
