I know very little about Ethereum. I'm trying to generate an Ethereum wallet in JSON format that will have encseed and ethaddr. I've been looking online and couldn't find a way to do that. Can someone tell me how to do that? Or generate a wallet like that for me with a known password?

  • can you pls help me how to bruteforce EthSale JSON files. My backup json files include encseed. Commented Aug 16, 2017 at 22:34

There are currently 3 formats for JSON files: EthSale, v1, and v3.

encseed is the encryption seed and is only found in the EthSale JSON files.

There are 2 methods that I know of to generate these formats:

  • You can use pyethsaletool which will generate a ETH sale wallet which has both encseed and ethaddr.

  • axic has made a cool tool called ethereumjs-wallet that handles a whole bunch of stuff pertaining to wallet generation and converting between various formats, including EthSale

The real question is why you want to generate a wallet like this? V3 is the current standard and what I would recommend. You can easily create that via geth or Ethereum Wallet.
