I created an ethereum paper wallet on an offline computer. Do I need to keep both the private key and the UTC/json file or can I just keep the UTC/json file and extract the private key from it. Thank you.

  • Note: If you forget your password, no one can do anything. It would be better if you keep your private key as your backup option.

The JSON file contains (in encrypted form) the private key, so that's all you need.
