33 | * TODO(TLS1.3): As and when official vectors become available we should use |
34 | * those, e.g. see | |
35 | * https://www.ietf.org/id/draft-thomson-tls-tls13-vectors-00.txt, however at | |
36 | * the time of writing these are not suitable because they are based on | |
1f6359db | 37 | * draft -16, which works differently to the draft -20 vectors below. |
