goEthereumWalletGen

goEthereumWalletGen is an ethereum wallet generator written entirely using Go. This application is Terminal-based and does not require an Internet connection, as it runs completely offline.

Requirements

Requires Go 1.18 or newer

Usage

There are two options to use the script (both require Go 1.18 or newer preinstalled)

Running the script manually using go go run *.go -pwd passwordToEncrypt -dir ./directoryToStoreKeystore -mnemonic "insert mnemonic phrase" -logging true

Make an executable using the makefile make build

And executing the program afterwards as follows ./ethWalletGen -pwd passwordToEncrypt -dir ./directoryToStoreKeystore -mnemonic "insert mnemonic phrase" -logging true

Flags

There are several optional flags one can use

• -pwd passwordToEncrypt
  • specifies a password to encrypt the keystore file with
• -dir ./directoryToStoreKeystore
  • Specifies the direcotry to store the keystore file in
  • default is ./wallets
• -mnemonic "my mnemonic key phrase"
  • One may use a mnemonic key phrase to generate a wallet off of
• -logging true OR false
  • logs privateKey and publicKey into the terminal
  • default is false

How the application works

The application generates a random private key using the elliptic curve digital signature algorithm if no mnemonic key phrase is given. In case a mnemonic key phrase is given using the flag -mnemonic, it uses that to get the corresponding private key from the key phrase.

After generating a private key, the application gets the public key from that private key and uses that public key to get the corresponding ehtereum account address. After that it generates a keystore file in the directoy specified by the -dir flag and prints the account address and the directory where it has stored the keystore file into the terminal.

Example

If run correctly, the program output in the terminal should look as following

PrivateKey: a389e66e50e200d0bfc97a72b3b6c8802b171bb8e4a898c7023931f99237d1f4

Ethereum Wallet (0x4B7ABF923484e0A66c045019B1dCf92333FB4FAA) has been generated and stored in ./keystores

Important

Never share your keystore file or privateKey with anyone!

Known Issues

The application will throw an error if one tries to generate an ethereum wallet with the same mnemonic key -mnemonic and directory path -dir phrase in a row. This is due to the program trying to create a keystore file which is already existant from running the program with the same properties beforehand.
