Crypto tangle

[Hal Murray]

We currently have 2 and 1/4 crypto packages.  That seems like the sort of 
things you like to clean up.

I would have said we have 2 1/2, but somebody deleted half of the 1/2.  I 
assume that was part of the --enable-crypto cleanup.  There used to be 
routines in libisc for MD5 and SHA1.  md5.c is gone, but sha1.c is still 
there.  There are also 2 header files in libisc/include/isc/: md5.h and sha1.h


We need sodium and OpenSSL.  I don't know much about either, but 2 seems like 
the wrong number.  Do we really need both?  If so, why?  I think we should 
have a paragraph someplace explaining why etc.

We also need pointers to the documentation.  I think I'd vote for a web page 
on our main web site with links to documentation for C99, POSIX, and all the 
packages we need.
