Hi,
I use Bitcoin core wallet to store my bitcoins. Is it possible to find the private keys for the addresses in my wallet? Also, is there a way to import bitcoins from cold paper storage? I know it is possible through something like blockchain to import a private key but I was wondering if there was a similar function for bitcoin core wallet?
Sure, there are some commands you should learn in order to deal with that. Have a look here
