Encrypted wallet versus private key. I think both are important; what's the main difference between these two?
If I have only the private key then I won't need the passphrase used to encrypt the wallet?
Private key is your "EVERYTHING" you dont need a wallet.dat if you have private key
But if someone gets your private key , they can access your onions readily.
Similarly, unencrypted wallet.dat is your EVERYTHING..
if someone gets your wallet.dat they can get all of your onions
Wallet passphrase to encrypt wallet so that if someone gets your wallet.dat, they will have to know your passphrase to unencrypt your wallet.dat before getting your onions
