How to use unencrypted mkey to derive all private keys by BIP32 path？

Question

The wallet is damaged, I only have the unencrypted master private key, How to recover the wallet?

Answer 1

There are tools like:

• the BIP39 tool: https://iancoleman.io/bip39/
• the BIP32jp https://bip32jp.github.io/english/

They take a so-called extended key (e.g. "xprv9tuogRdb5YTgcL3P8Waj7REqDuQx4sXcodQaWTtEVFEp6yRKh1CjrWfXChnhgHeLDuXxo2auDZegMiVMGGxwxcrb2PmiGyCngLxvLeGsZRq") as input and output corresponding private keys that can be copied to Bitcoin Core using RPC importprivkey in order to replicate a wallet.
