Construct an experiment to estimate the speed at which a particular computer can process an authentication password. From that estimate, determine how long it would take to test common password candidate lists, such as a list of $100$ or $1000$ popular passwords, the same list enhanced with orthographic substitutions $(3$ for e$,$ zero for O$,$ one for l$,2$ for z$,$ and so forth$),$ and a word list from a common online dictionary. There is no single right answer to this question. The point of the question is to perform the analysis to determine the number of possibilities and the rate at which those possibilities can be checked.
