The Intro Security class I took at UMich we did a month or so all on crypto and the relevant attacks against it. Never implemented any algorithms but every assignment involved breaking bad implementations of crypto or various applications which was extremely interesting. Pretty much every lecture slide had a disclaimer "never implement * yourself, Use respected crypto libraries!!!".
