Not hard to win if everyone is being reasonable. Given an auditor that thinks all uses of MD5 are proscribed, what would you put the odds of them being reasonable at?
ETA: per 'kbenson it's not hard to conceive of a situation where proscribing MD5 is reasonable. Taking 'skissane's account at face value is probably reasonable, but my implicit assumption that the auditor would not explain if pressed isn't being charitable.
