Hi, the dumpwallet command throws the private keys and a xprv.
Can I use it to derive all future addresses from the wallet?

So long as you do not change your password or set one. If you do, the xprv will change.

I'm a bit out of sync, I didn't know the reference client implemented HD keys.

Only in 0.13.0+

If so, could anyone tell me the derivation path used?

It uses the standard paths as defined by BIP 32. That is m/0/0/k for addresses you get from the wallet, and m/0/1/k for change addresses.

Thank you for the reply, I was able to derive correctly.

So... if I have a wallet without a password and create one or change the password, why does it change the master private HD key?
Given it had already derived private keys and addresses that might already been used, what happen to them?
Are they added as independent keys? So if I don't back them up, I wouldn't have access to funds, correct?
