| 8 # authentication. Outputs for automated tests are stored in | |
| 9 # net/data/ssl/certificates, but may be re-generated for manual testing. | |
| 10 # | |
| 11 # This script generates two chains of test client certificates: | |
| 12 # | |
| 13 # 1. A (end-entity) -> B -> C (self-signed root) | |
| 14 # 2. D (end-entity) -> E -> C (self-signed root) | |
| 15 # | |
| 16 # In which A, B, C, D, and E all have distinct keypairs. Both client | |
| 17 # certificates share the same root, but are issued by different | |
| 18 # intermediates. The names of these intermediates are hardcoded within | |
| 19 # unit tests, and thus should not be changed. | |
