test_bip32_vectors covers BIP32 vectors 1 and 2 only. Vectors 3 and 4 test retention of leading zeros in a private key and hardened derivation over such a key — the cases implementations have historically got wrong.
Both run against the existing API; no new capability is needed.
test_bip32_vectors covers vectors 1 and 2 only. Add vectors 3 and 4 from
BIP32, which exercise retention of leading zeros in a private key and
hardened derivation over such a key. Both run against the existing API.
