I'm going to do the forensics.
I don't want to generate the private key, like that bip39 mnemonic converter does. It's risky and unnecessary.
I will use the pubkey.
Where is a tool that I can use to generate the list of addresses from the pubkey?
You can try
http://bip32.org/ or
https://dcpos.github.io/bip39/It would probably be easier to import pubkey to some wallet, for example Electrum.
