# This script generates two chains of test certificates:
#    1. A1 (end-entity) -> B (self-signed root)
#    2. A2 (end-entity) -> B (self-signed root)
#
# In which A1 and A2 share the same key, the same subject common name, but have
# distinct O values in their subjects.
#
# This is used to test that NSS can properly generate unique certificate
# nicknames for both certificates.
