Refer to doc/proposals/2021-11-remove-arbitrary-bytes.md for details.
Since our proposal left the exact terminology undefined, this commit
took a stab at that. The main idea was to keep referring to what we
have in a leaf and what is being signed as a _checksum_. This ensures
that we are not undermining or stepping away from our core of "signed
checksums". It seemed quite natural to refer to a checksum's preimage.

It did not become part of the SSH signing format proposal after all.

Sigsum logs should now use open-ended shard intervals.
|
|
|
|
|
| |
We get the remove arbitrary bytes proposal "for free" when switching to
a signing format that is backwards-compatible with SSH signatures.
|
|
|
|
| |
We decided to implement open-ended shard interval on 2021-11-23.

Punting on all crypto agility for now. Let's make a separate proposal
out of the contents of the section "Related questions".

After our refactor rate limits are no longer mentioned in §3. The
domain hint subsection contains that text now, and should therefore be
before the shard hint subsection that assumed it is already explained.

These questions are to some extent answered as part of our refactor, or
addressed as things we are still open to think more about. I think we
can leave them out for now and add them later _with answers_ if needed.
I kept the privacy concerns question because that is not addressed
anywhere yet. We think that the answer is "mostly none".

To be re-added at a later time somewhere else. It is not helpful for a
reader that is trying to understand the basic design for the first time.

I don't think it improves our design document by being moved. We
already have a summary of properties in the introduction, and an easier
primer at the start of Section 3 that is strongly coupled to Figure 1.
Perhaps it is no longer necessary though. When we wrote this we did not
have a summary of properties in introduction, or a relatively detailed
walk-through of the log's intended usage-pattern.
I'm fine with both keeping as is or deleting if it feels redundant.

- Deleted unnecessary roadmap
- Clarified distribution and verification section
- Proposed down-to-the-point text for domain hint description
- Left comments that we should consider addressing
- A bunch of minor edits
For transparency this commit was squashed and rebased by rgdd.

There is a risk that "the right data" is confused with "what do you
mean, obviously it is the right data if there is a valid signature".
Tried just reword.

The claimant model was mostly pulled from this document. It is useful
to define use-cases of sigsum in a succinct way, but not helpful to tell
the reader about the concrete design that we have for a sigsum log.
(We still have a separate document that uses the claimant model.)
This refactor also tries to remove focus from use-cases that in general
are messy, and instead focus on the simple sigsum logging design that
has a very well-defined and thought-through usage-pattern. The result
of this is that things should be a little bit more down-to-the-point.

I think the claimant model is most helpful for us to describe the
different use-cases of a sigsum log. Let's focus on claimant models for
use-cases in this document, not claimant models for logs _as well_.
I kept R-B as an example because it is concrete, and fixed the long-due
updates that GeKo pointed out a while back about, e.g., "right data".
