Getting past the most basic physical security of all: Learning to pick locks at DEFCON 22

Lockpicking Village at DEFCON 22 was run by TOOOL (The Open Organisation of Lockpickers) The village gave brief presentations every half hour or so to offer the basic information necessary to understand how lockpicking works. The concept is relatively simple: a lock consists of a certain number of spring-loaded pins (typically anywhere from two to six) of varying lengths lined up in a plug, and each pin needs to be pushed up by the lower pin above a certain point, known as the shear line, to “bind” or stick into place.”]
