listaddressgroupings rpc command will export address list, and you can dump the private key one-by-one with dumpprivkey command.
Right. Understood. But I also very clearly stated in my OP that I'm aware of that, but thats a LOT more work than it would be IF the password were recoverable. In addition, 81 LTC sitting in a locked wallet that uses the same passphrase that I'd prefer not to lose.
I'm fully aware I can export all the info. Exporting it all, doing it by hand, manually reimporting all the addresses is a lot more work than recovering the password if possible. And again, 81 LTC in another wallet.
I understand most lost passwords are a lost cause without months of brute forcing. This is a special case in that I have the unlocked wallet with the password in memory, and I also have a before and after private key to compare.
Thats what I'm tring to see if possible.
