Cryptographers are great guys and smart people, but why don’t they ever produce code that solves the problems we have, and why do the whine when we do ?

MD5crypt, probably the worlds most widely used protection of passwords, was thrown together by a non-cryptographer in an afternoon, why did he have to ? (and why isn’t he too proud of it ?)

GBDE , an encrypted disk facility, took considerably more work in the second step of the Feynmann algorithm, and a solid beating from the cryptographers card-carrying union members, but did anybody learn anything and if so, what ?
