Maybe it's better to organize things differently -- make `file/sha1'
provide the openssl functionality or the racket version (which will
move to a private subdirectory)?  This looks like a better layout
since it's easier to make it possible to remove openssl, and I think
that a `file/sha1' is more visible, so people are likely to use it
