How to import private keys - TheDAO/DAO-1.0 GitHub Wiki
Paste the key into a text file, save it to disk and use the path to that file with geth account import.
For all operating systems:
In order to import a private key, you need geth, the command line client for the ethereum node. geth resides in a subfolder of the MIST Wallet. When you download the mist wallet, you'll unzip the release file to a folder with the name "Ethereum-Wallet-osx-version" (osx stands for the operating system, version is the tree digit version number). Inside the folder navigate to the subfolder resources/node/geth. In this folder there is only one file, the geth runtime.
Before running geth, the MIST Wallet should be stopped. Then run ./geth account import privekey-file.txt.
