I got a wallet from https://www.myetherwallet.com/ and then I downloaded all the files (keystore, qr.pdf and private key). Then I compressed (zip) these files using a password I can't remember (yes, that's stupid).

So basically I have the public key, the name of the keystore file and the password of the keystore file. What would you recommend to recover the private key ?

So far I tried fcrackzip with a dictionary of passwords I usually use. But no success... I wonder if there might be another way of recovering these files.

  • Can you download the wallet from MEW again? – 0xcaff Jun 13 '17 at 23:16
  • How could I do that ? – debzsud Jun 18 '17 at 9:05
  • I guess you can't. Have you imported the wallet into other ethereum clients? – 0xcaff Jun 18 '17 at 19:02
  • No... I was hoping that with the current information I had I could recover the wallet – debzsud Jun 19 '17 at 7:28

I would write this in the comments, but I can't yet because I don't have 50 rep yet, so "an answer" it is!

Do you remember anything about your password? That would greatly improve your chances of recovering the funds. You could create a custom word list tailored to what you remember.

You can use John The Ripper Jumbo (actually a community edition of the software) which supports cracking password protected ZIPs.

This is going to be a process that requires knowledge (working with command line tools, a lot of googling) and a ton of CPU/GPU power.

  • Thx, I tried building my own zip cracker in python but it seems that I used a really strong and unusual password.. Thanks for the link btw – debzsud Jun 19 '17 at 7:29

    @debzsud Be aware that sending the compressed zip file to that eric may allow him to steal your money. – Penquin Jun 24 '17 at 9:55
