I used the script from this post
To get the Master Private Key, Extended Private key at index 14, and WIF format of that key.
All those values correspond to the user seed and user public key.
I need to do the same with the shared encrypted seed (and shared public key) but I am not sure I know the correct password used to encrypt the shared seed.
Looking at the coinbase multisig github they specifically state they used the BIP38 library to decrypt the encrypted shared key seeds.
Is there any way I can test passwords to decrypt the shared seed? I assume testing should de done offline, right?
Also, I have no idea what "Extended Private key at index 14" even means in this context. What does that mean?
Thanks in advance.
