Kerckhoffs's principle was proposed by Dutch cryptographer Auguste Kerckhoffs in 1883, asserting that a cryptographic system should remain secure even if everything about the system, except the key, is public knowledge.

VerifiedKerckhoffs's principle holds that the strength of a secure system should not depend on the secrecy of its design, but on the secrecy of the key.78% similarUnverifiedIn his paper "Communication Theory of Secrecy Systems," Shannon proved that the one-time pad is the only encryption scheme satisfying perfect secrecy, and that the key must be the same length as the plaintext and used only once.68% similarUnverifiedSecurity through obscurity refers to the practice of preventing attackers from discovering vulnerabilities by hiding a system's implementation details, code logic, or architectural design.68% similarUnverifiedThe core mechanism of a password vault is to decouple keys from how they are used—agents hold reference handles rather than plaintext keys, and the actual credentials are dynamically injected into the target system by the vault at runtime.67% similarUnverifiedThe Enigma's encryption mechanism is fully understood, but some historically intercepted ciphertexts cannot be completely recovered due to missing context, absent keys, or signal corruption.66% similar
