Am wondering now it if makes sense to create a new directory with:
hash/*
section (or something in crypto) where I cull things/move out of the current
apr_random, sha256_glue and apr_md4/5 and apr_sha1 - and
then all give them below treatment.
It would make wiring them up to OS specific things or to
nss/openssl/CommonCrypto also a bit easier.
And then perhaps come up with a few extra apr_hash things that do a subset of
what we currently do in the various apr_sha/md’s.
Or is that not worth it - as mid to long term md4/md5 and sha1 will evaporate.
