By the private keys do you mean just the password I chose? or is it like in bitcoin wallets where they give you 10 random words? because i don't remember if I got any of those.

Then Go to HELP>> Debug Window
Click on Console
Type dumpprivkey Onion Address and press enter
It should show your private key too you
It worked for me when I did it.
