Bitcoin HD Wallet Generator

This is a C# .NET 7.0 console CLI tool that generates Bitcoin addresses and writes the results to the console. It uses the NBitcoin class library to create the Bitcoin keys and public addresses.

Create keys in an Offline Environment

When generating crypto wallets, it is important to do so in an offline environment to ensure maximum security. This is because an online environment is more susceptible to hacking and other forms of cyber attacks. Additionally, it is important to securely store the 12-word mnemonic in a safe and secure place, such as a password manager like KeePass. KeePass is completely offline with encryption, which provides an added layer of security for your mnemonic.

IMPORTANT: The private keys and specifically the 12 word phrase should be kept private and not shared with anyone, as it gives access to the funds associated with the wallet.

Using the Command Line Tool

To use the command, you will need to install the NBitcoin class library via Nuget. The command to install is:

Install-Package NBitcoin    
or   
dotnet add package NBitcoin

Once the library is installed, you can run the command by typing the following into the console:

BtcKeyGenerator

Running this command will generate the Bitcoin address and display the output to the console.

Program Output

The output of the program will dump the following data:

  • BIP39 Mnemonic:

    • This is a 12-word seed phrase that is used to generate the private key. It should be kept in a safe and secure place and is the only thing you need to restore your wallet at anytime.

  • BIP39 Seed:

    • This is a 128-bit seed that is used to generate the private key.

  • BIP32 Root Key:

    • This is the master private key that is used to generate the other private keys.

  • BIP32 Derivation Path:

    • This is the path that is used to generate the other private keys.

  • BIP32 ExtPubKey:

    • This is the extended public key that is used to generate the public addresses.

The program will also display a list of derived public addresses in the format:

[derivation path], [public address], [public key], [private key]

Example Output

Derivation Path ->  Public Address  ->  Public Key  ->  Private Key

Since the 12-word phrase is all you need to restore your wallet you must keep that secure and encrypted. You can save the public address and use these addresses to receieve Bitcoin. It is good practice to use a new public address for each transaction to ensure privacy.
