For those that care about references - NIST Special Pub 800-57 Part 3 only
has more specific recommendations about key management but refers to Part 1
for all general pointers like key lengths, hash algorithms to use for
specific security strengths, etc.

So 800-57 Part 1 has all the necessary information, just in a non-DNSSEC
specific format.

As discussed here on namedroppers, I removed the section about how SHA1
signatures should be ignored, and only refer to RFC4035 section 2.2 as
protection against downgrade attacks, which should be enough.

I also removed the informational reference to NIST SP 800-57 part 3,
which unfortunately has not been released in time. Instead I just made
that reference to SP 800-57 in general.
