How to import a plain private key into geth or Mist?

  • This is such a basic question, but I can not figure out how to import a plain, unencrypted private key into geth or mist?

    I tried geth account import 7[......]bla but it seems this command is always looking for an unencrypted keyfile.

    Any ideas?

  • Paste the key into a text file, save it to disk and use the path to that file with geth account import. Here are some example Windows instructions that might help:

    1. Open Notepad
    2. Paste key into notepad without any extra characters or quotations
    3. Save the file as nothing_special_delete_me.txt at C:\
    4. Run the command, geth account import C:\nothing_special_delete_me.txt
    5. After successful import, delete the file at C:\nothing_special_delete_me.txt

    If you do not have geth installed already, do the following steps after step 3, and the continue to step 4:

    • Open command prompt (cmd.exe).
    • Inside the Command Prompt, type the following command to go to the folder containing your Geth.exe file: cd c:\Ethereum-Wallet-win64-0-7-3\resources\node\geth (insert your correct path there)

    I am getting `Fatal: keyfile must be given as argument` while doing the same. PS: I am running on linux macine.
