+# This script generates several forms of test certificate chains, used to test
+# how the platform handles path building and revocations. They are designed
+# to mirror how the WebPKI has evolved.
+#
+# Letters annotate which subject & key is used, while numbers indicate
+# the issuer (e.g. C1 and C2 share the same subject & key, but have different
+# issuers). They are ordered from leaf to root.
+#
+# Tests for basic path building (e.g. when E is trusted, but D is not)
+#     1. A -> B -> C -> D
+#     2. A -> B -> C2 -> E
+#
+# Tests for basic intermediate revocation (e.g. when the client trusts both
+# E and F).
+# Note: To fully test for the cases, it's necessary to massage the structures
+# so that the various library sorting routines 'prefer' the revoked path first,
+# such as by modifying the issuance dates.
+# The goal is that for both cases, the client will find/use either paths #1 or
+# #2, despite being presented (by the server) with paths #3 or #4.
+#
+#     3. A -> B -> C3 [revoked by F by issuer & serial] -> F
+#     4. A -> B2 -> G [revoked by F by SPKI] -> F
+#
+# Tests for cross-certified hell - such as when roots mutually certify,
+# creating a potential 'loop'.
+# In this case, a version of J2-signed-by-K exists, as does a version of
+# K2-signed-by-J (thus, a loop). In addition, self-signed versions of both J
+# and K exist, which reflect what happens when OS stores phase out one root
+# while phasing in a new root.
+#
+#     5. H -> I -> J
+#     6. H -> I -> J2 -> K [revoked by SPKI]
+#     7. H -> I -> J2 -> K2 [revoked by SPKI] -> J
+#     8. H -> I -> J2 -> K2 [revoked by SPKI] -> J2 -> K [revoked by SPKI]

The complexities of these chains are for the inevitable NSS tests (see
https://crbug.com/472978 and
https://ssl-tools.net/subjects/7cb166549cabdb44ee622616adf4657bf77ad594 for how
the cycles are structured ), but I wanted to make sure the Windows code all
handled these cases fine (it does; the ROOT store has a greater priority queue
in the Collection Store that is used for chain building, and so it trumps the
notBefore sorting that Collection Stores normally use for Find operations, since
Find is ordered by Priority -> StoreCallback, where StoreCallback is dependent
on whether it's CRL, CTL, or Cert)

[Incidentally, this became so much easier to understand once I realized to draw
this out with certificates as edges between nodes rather than nodes.]

[davidben, 2016/01/21 02:37:39]

Wouldn't it be equally unnecessary for C2 to sign B? (I'm not clear on what the
comment is here for.)

[Ryan Sleevi, 2016/01/21 02:54:05]

See line 144 for the same comment

The AKI/SPKI issues are because of NSS preferences that I need to test and
validate.

Why does this and the one below have AKI, but not the others?

[Ryan Sleevi, 2016/01/21 02:54:05]

Blergh, this was debugging for CAPI and how it handles trust anchors, and me
trying to force it to explore a J2/K2 loop, but it was too smart.
