user15314: I've got some Go code that successfully generates private keys and vanity addresses as described by the wiki.
So I have all the parameters around the private key but I'm not sure what to do with that info to make it usable by the bitcoin core application.
Should I build a wallet.dat file to point the wallet software at? What's the format for that file? Is there an alternative format so I can import my new key alongside my old keys instead of replacing the existing file so that the software has more control of what the structure of the wallet.dat is?
I could layout the key in the same format that paper wallet QR codes use but I'm not sure what I'd do with that string for a desktop computer to accept it.
What format should I put the raw private key into and where should I put it for wallet software to use it?

user56876: In Core, go to "Help" and "Debug Window". Go to the console and type importprivkey [key]. This might also interest you: How do I import a private key into Bitcoin-Qt?
