Generating your own BTC and ETH Wallet

[krashfire]

I saw some comments looking for a sample btc wallet with private and public key so you can run your programs on some samples or you just want to create a wallet so you can be anonymous.


 i created the btc program that can generate 10 sets of btc address that can give you the btc and eth address from 1 hexadecimal private key.

you can download it here.

Code:

    private_key = ecdsa.SigningKey.generate(curve=curve)

not good. what's used for rng seed here? you'll never know. It should be system-dependent at least like in bitcoin core  they use last windows messages to do so


src/qt/winshutdownmonitor.cpp

Code:

bool WinShutdownMonitor::nativeEventFilter(const QByteArray &eventType, void *pMessage, long *pnResult)
{
       Q_UNUSED(eventType);

       MSG *pMsg = static_cast<MSG *>(pMessage);

       // Seed OpenSSL PRNG with Windows event data (e.g.  mouse movements and other user interactions)
       if (RAND_event(pMsg->message, pMsg->wParam, pMsg->lParam) == 0) {
            // Warn only once as this is performance-critical
            static bool warned = false;
            if (!warned) {
                LogPrintf("%s: OpenSSL RAND_event() failed to seed OpenSSL PRNG with enough data.\n", __func__);
                warned = true;
            }
       }

       switch(pMsg->message)
       {
         .....

it's '17 bitcoin but sure it stays the same. File was unvisited for 5 years or so that time.

I like the idea and the implementation. I haven't checked the technical aspect of the code, but the structure and the outcome look good.

I have a similar BASH script in my signature. You can check it out in case you find it interesting too.

Interesting, but I'll give you some opinions and if you want, you can implement them in your code to get better and better:

Do you know the BIP39 iancolaman website? It's a website that generates a mnemonic, seed, xprivs, derived keys, addresses, etc. It would be great to have a tool like this without needing to be on the website. It's possible to create this all in a script and run it on your machine.

It'd also be interesting for the script to generate all types of existing bitcoin addresses:

Code:

legacy - p2pkh
p2sh-segwit - p2wpkh-p2sh
bech32 - p2wpkh (native segwit v0)
bech32m - p2tr (taproot - native segwit v1)

Another similar interesting site for you to base yourself on, each with one more or less functionality:

https://bitcoiner.guide/seed/
https://gugger.guru/cryptography-toolkit/#!/hd-wallet

I don't advise anyone to generate wallets based on scripts we find out there, especially from strangers (unless you know how to review the code), as a bug could happen that could make you lose your funds.

But as long as you only use it for learning and testing, it's fine.

There are several similar scripts that we can find here on the forum and on this board.

you mean like a stand alone? ahh. nice... ok. i will get back to you on this. interesting.
