Can the addresses generated by "addresstypes.php" not be the same?

Can the addresses generated by "addresstypes.php" not be the same?

[afk11]

The example has a fixed private key. You want a random one instead? https://github.com/Bit-Wasp/bitcoin-php/blob/1.0/examples/privatekey.php and review methods in PrivateKeyFactory.

[wartw]

I want to generate multiple isolated addresses using a fixed set of private keys. Is there a way to do this?

[afk11]

Look into bip32 "HierarchicalKey" in this lib. Check over the BIP so you understand what it does https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki

[wartw]

I do understand there is an error it?(GOOGLE translation may be a bit off-topic) https://github.com/Bit-Wasp/bitcoin-php/blob/1.0/examples/bip32.php

//Generate private key
$hdFactory = new HierarchicalKeyFactory();
$master = $hdFactory->generateMasterKey($random);
//Main address
echo "Master key (m)\n";
echo "   " . $master->toExtendedPrivateKey($network) . "\n";

//Generate public key
$masterAddr = new PayToPubKeyHashAddress($master->getPublicKey()->getPubKeyHash());

//Block address
$key1 = $master->deriveChild(0);
//Block 999999 address
$key2 = $key1->deriveChild(999999);

[afk11]

Is there an error? share it?

You should check out BIP44 as well by the way (or bip49, or bip84) They all do the same thing, but the difference is the address types.

Electrum supports these wallet formats too!

I get up and continue to study, now it is 3 am in Taiwan time (I should take a break

Am I misunderstanding something?

[wartw]

I don't understand which sign of bip2 should I use to sign the transaction

[afk11]

This is a very obvious PHP error, what is confusing about it? I'm not here to do your job.

I don't understand which sign of bip2 should I use to sign the transaction

What is "Sign of bip32"?

[wartw]

Google translation, may misunderstand what I mean! My address is generated by bip32. I have successfully received the money. I need to transfer it now, but I do n’t know what to get the signed key.

[afk11]

$key1->getPrivateKey() gets the privkey from a HD key. Then you use the privkey to sign, like the last time.

[wartw]

OK, if I use
 $ key0 = $ hdFactory-> fromExtended ("xprv9vk7fGTQx3oxxxxxx"); // existing xprv $ key = $ key0-> toExtendedPrivateKey ($ network); 
$ key1 = $ key0-> deriveChild (0); 
$ key2  = $ key1-> deriveChild (999999);
 Use "$ key2-> getPrivateKey ();" to sign?

[afk11]

It depends where you sent the funds. If you made the address from key2, then you should sign with key2.

[wartw]

I'll get up tomorrow and try it out, thank you for helping me speed up a lot of development time. I have also studied for more than half a month before I understand that OUTX is the last transaction TXID (I know this is funny

[wartw]

I succeeded! !!
