How can i figure out the private keys from these information please?
If you've provided the passphrase, the WIF private keys will be listed under the "keys" json array (usually above that master key array).

It contains "addr", "compressed", "encrypted_privkey" down to "secret",
the one that you're looking for are the "sec" above secret, which is the WIF prvKey of the address above it.

But if you see this line:
Code:
The wallet is encrypted but no passphrase is used
Then there'll be no WIF keys listed there.


Yep I understand it.
But everytime I get to add the password it says : segmentation fault.
How can i make it work?
Thanks  you for your time.
