7# This script generates two chains of test certificates:
8#
9#     1. A (end-entity) -> B -> C -> D (self-signed root)
10#     2. A (end-entity) -> B -> C2 (self-signed root)
11#
12# in which A, B, C, and D have distinct keypairs. C2 is a self-signed root
13# certificate that uses the same keypair as C.
14#
15# We use these cert chains in
16# SSLClientSocketTest.VerifyReturnChainProperlyOrdered to ensure that
17# SSLInfo objects see the certificate chain as validated rather than as
18# served by the server. The server serves chain 1. The client has C2, NOT D,
19# installed as a trusted root. Therefore, the chain will validate as chain
20# 2, even though the server served chain 1.
