Is OB affected by the BIP39 bug?

[JustinDrake]

OpenBazaar makes use of BIP39. See discussion iancoleman/bip39#58

[bip32JP]

BIP32 bug actually

Specifically in hardened key derivation where private keys are not properly padded when the MSB is a 0x00 byte.

This means there is a 1/256 chance that this bug occurs on any BIP32 wallet that contains hardened derivation.

From that thread it seems as though wallets built off of bitcore are affected due to the dropping of the byte. We're building off of btcd so I'm not sure of this affecting us. @cpacia ?

[hoffmabc]

So the answer is no problem?

I think btcd handles the padding correctly. I get 17rxURoF96VhmkcEGCj5LNQkmN9HVhWb7F from that test vector which is consistent with the others.
