the various keys are in a tab there called permissions
for private posting key you must click a button to reveal it
these keys represent different authority for kinds of actions on your account, kind of like an API, and the posting key is the most secure of these because it does not allow the app to access any funds, transfers, altering profile, etc. The most common scenario is using the posting key for something that either votes on your behalf, or is used as an alternate interface where you will be selecting posts to vote on. You should NEVER give out your master/owner key, be very paranoid of active key since it can access funds, and finally you should keep track of all the places you use your posting key.
