Rubber-hose cryptanalysis

Rubber-hose cryptanalysis is a term used to describe a method of obtaining secret information, particularly cryptographic keys or passwords, through coercion or torture. The name derives from the idea that someone might use a rubber hose to inflict pain or threaten physical harm in order to extract information from an individual. Unlike traditional cryptanalysis, which focuses on mathematical techniques to break cryptographic systems, rubber-hose cryptanalysis relies on human factors and the vulnerability of individuals to persuasion or force.
