you know, these are pretty good points. i personally don't like
bcrypt, but it is undoubtedly delivers what it promises. and also you
can find a lot of applications and a lot of love for it. i myself
implemented it, and i've never read the original paper. i used the
openbsd source and 3rd party implementations. for all i care, the
original paper could be in chinese. i was able to implement keccak
based on the papers, but only after a lot of trial and error. yet,
keccak was selected anyway, for the soundness of the *algorithm*.
