A few questions about private key's. I generated a public walletaddress and a private key on guldencoinpage of https://walletgenerator.net/ as a test.

When I want to use the private key is that acting like a normal walletaddress and acting for sending coins from the public address? It has way more numbers than the normal addresses. And how to import it in the windows client. Maybe silly questions, never worked with private keys
