I have my public & private key (generated with MyEtherWallet), however, I forgot to create a keystore file, which would make my online access to the wallet a bit safer if I'm correct.

I got to install geth.exe on my offline computer, and

geth account import e:\rawprivatekey.txt

works, but only returns the public address. I can't seem to get it to regenerate a keystore file! Does anyone know how to do that?

When you import a key in geth it automatically creates a json wallet.

You can list existing wallets with geth account list.

A list should be like this:

Account #3: {59cc3d2701a69e2f006a47e412092d1274f81d58} keystore:///home/ubuntu/.ethereum/keystore/UTC--2018-01-28T05-19-52.363512148Z--59cc3d2701a69e2f006a47e412092d1274f81d58

The file pointed by the keystore is your json wallet you can copy and rename to some other place.

  • hmm... I only get a list of 3 (same) addresses in the parantheses, but no keystore information along with it.. I have to add that I'm offline and using Windows. Maybe the Windows version of geth.exe is different. – richey Jan 28 '18 at 23:04

If you want to generate keystore file and you have a private key, you can use web3.py (^4.0.0b6).

There is a module called Account and in this module there is a method called encrypt.

Account.encrypt(private_key, password)

Creates a dictionary containing your private key, encrypted by the supplied password. If you want to create a keyfile recognized by Ethereum clients like geth and parity: encode this dictionary with json.dumps() and save it to disk where your client keeps key files.

Yes, web3.js doesn't have it, but web3.py does

  • ok, I can install python for it, but where to find web3.py? (sorry, noob here) – richey Jan 26 '18 at 1:33
  • web3.py docs Quickstart. – Roman Frolov Jan 26 '18 at 1:35
  • I, personally, use PyCharm, so I just go Settings > Project Interpreter > Install > web3 – Roman Frolov Jan 26 '18 at 1:36
  • sorry, I can't figure it out. I have installed PyCharm on my offline computer now (the point I want to regenerate the keyfile is to avoid being forced to enter my private key in an online browser!), but web3.py isn't found that way. Guess it has to be loaded over the Internet (which it is offline from in my case). Can I manually add it somehow, or is there another method to regenerate the keystore file from the private key? – richey Jan 27 '18 at 1:43
  • I’m afraid there are no other methods to recover keystore file. – Roman Frolov Jan 27 '18 at 9:58
