Hello,

You accidentally deleted your keystore-file or exported your private-key from another wallet which didn't provide a keystore-file?
No problem, you can simply generate a new one. Some of you may think you can just download your keystore-file using the 'View Wallet Info'-Tab, but this only works if were using your keystore-file as login-method.
If you're using your private-key there won't be any option for downloading your keystore-file.

Now why should you even use the keystore-file if you've already got your private-key? Thats simple. The keystore-file is encrypted and requires a password while the private-key is plaintext and doesn't require any further authentication.


To generate yourself a new keystore-file you'll need:
- Your private-key
- Google Chrome (Download: https://www.google.com/chrome/index.html#)

Install the official MyEtherWallet-Chrome-Extension
Link: https://chrome.google.com/webstore/detail/myetherwallet-cx/nlbmnnijcnlegkjjpcfjclmcfggfefdm?hl=en
(You can also find this link by clicking on 'MyEtherWallet Chrome Extension' in the lower right of the MyEtherWallet-Website)


Open the MEW extension and click "Add Wallet"



You'll be redirected to the MyEtherWallet-Website.

Select the "Private Key"-Checkbox, then enter your private-key and click "Unlock".



Next assign a "name" and a password (the password will be the password for your keystore-file) and add the wallet.



Now open the extension and click "My Wallets".



You'll be redirected to the MyEtherWallet-Website - click on the "View"-icon for your wallet



Enter your password and click "View Wallet Info".



Now just download your keystore-file Smiley

Hello,

Well, I guess there may have been some changes in the meantime as I wrote this guide one year ago.
However I will have a look and update the guide as soon as I find a solution - just give me a few minutes and I'll report back Smiley

Best regards,
Nestade

very helpful article, thank you. therefore, I stand guard by backing up my keystore file, between the PC and the external hard drive. so I'm calmer by having a back-up.

Thank you very much for your feedback Smiley
There might be even more methods to encrypt your private-key but I guess the one I provided is quite easy and doesn't require any shady 3rd-party-tools.

Just realized that there even seems to be a guide on the MEW-website:

This is a good insight and procedure
But for newbies please ensure you do not try this if you do not understand how it works

You can secure your MyEtherWallet the Normal way by protecting your private key

I think it is quite risky to submit your private key on other website to get the keystore.
Just use your metamask and import the wallet using private key you own.
Honestly, using private key or keystore everytime you login is not a good way to using your wallet.

I rarely use MEW, saving the keystore-file or private key on the computer is very unsafe. Moreover, managing many wallets with MEW is quite complicated

UPDATE:

Hi,
I tried the method you shown below but the unlock button did not appear when I entered my private key. Do you what I did wrongly here?

Thanks.

Open the MEW extension and click "Add Wallet"
