<p> <strong> Barry Wels </strong> earned his nickname “The Key” when he started picking locks around 1985. He cofounded the infamous Dutch hacker magazine <em> Hack-Tic </em> where he first started publishing articles on lockpicking. He has done talks and workshops at numerous European hacker events and at HOPE conferences for nearly two decades, operates a security consulting company, and is also cofounder of Cyptophone, a secure mobile phone company. As with mechanical locks, Barry believes in security through transparency, not obscurity. </p>
