如何在不使用 API 的情况下生成 Trx 钱包

Question

基于 TRX documents 和 GitHub 中的一些搜索 我尝试离线生成钱包，但由于某些原因我无法使用 API。

根据 Trx 文档，我应该执行以下步骤：

1. Generate a key pair and extract the public key (a 64-byte byte array representing its x,y coordinates).
2. Hash the public key using sha3-256 function and extract the last 20 bytes of the result.
3. Add 0x41 to the beginning of the byte array. The length of the initial address should be 21 bytes.
4. Hash the address twice using sha256 function and take the first 4 bytes as verification code.
5. Add the verification code to the end of the initial address and get an address in base58check format through base58 encoding.
6. An encoded Mainnet address begins with T and is 34 bytes in length.

Please note: the sha3 protocol adopted is KECCAK-256.

我在 GitHub 中找到 mattvb91/tron-trx-php 并且这个存储库有一个钱包生成器方法 /src/Wallet.php 但是生成的密钥验证 return 一个错误异常和验证失败。

我尝试重新编写 mattvb91/tron-trx-php 钱包生成器方法并创建我的钱包生成器

class walletGenerator
    {

        private $addressPrefix = "41";
        private $addressPrefixByte = 0x41;
        private $addressSize = 34;

        public function __construct()
        {

        }

        public function generateWallet()
        {
            $key = new Key();

            $odd = false;
            while (!$odd)
            {
                $keyPair = $key->GenerateKeypair();
                if(strlen($keyPair['public_key']) % 2 == 0) $odd = true;
            }

            $privateKeyHex = $keyPair['private_key_hex'];
            $pubKeyHex = $keyPair['public_key'];

            $pubKeyBin = hex2bin($pubKeyHex);
            $addressHex = $this->getAddressHex($pubKeyBin);
            $addressBin = hex2bin($addressHex);
            $addressBase58 = $this->getBase58CheckAddress($addressBin);
            $validAddress = $this->validateAddress($addressBase58);

        }

        private function getAddressHex($pubKeyBin)
        {
            if (strlen($pubKeyBin) == 65) {
                $pubKeyBin = substr($pubKeyBin, 1);
            }

            $hash = Keccak::hash($pubKeyBin , 256);
            $hash = substr($hash, 24);

            return $this->addressPrefix . $hash;
        }

        private function getBase58CheckAddress($addressBin){
            $hash0 = Hash::SHA256($addressBin);
            $hash1 = Hash::SHA256($hash0);
            $checksum = substr($hash1, 0, 4);
            $checksum = $addressBin . $checksum;
            $result = Base58::encode(Crypto::bin2bc($checksum));

            return $result;
        }

        private function validateAddress($walletAddress){
            if(strlen($walletAddress) !== $this->addressSize) return false;

            $address = Base58Check::decode($walletAddress , false , 0 , false);
            $utf8 = hex2bin($address);

            if(strlen($utf8) !== 25) return false;
            if(strpos($utf8 , $this->addressPrefixByte) !== 0) return false; // strpos(): Non-string needles will be interpreted as strings in the future. Use an explicit chr() call to preserve the current behavior

            $checkSum = substr($utf8, 21);
            $address = substr($utf8, 0, 21);


            $hash0 = Hash::SHA256($address);
            $hash1 = Hash::SHA256($hash0);
            $checkSum1 = substr($hash1, 0, 4);

            if ($checkSum === $checkSum1) {
                return true;
            }
        }

这是我的问题：

1. validateAddress 方法出现错误异常
2. 当我在 Trx 钱包中手动添加私钥时，检测到的钱包地址与生成的地址不同。

if(strpos($utf8 , $this->addressPrefixByte) !== 0) return false; // strpos(): Non-string needles will be interpreted as strings in the future. Use an explicit chr() call to preserve the current behavior

补充信息

我使用 ionux/phactor 生成密钥对，iexbase/tron-api 支持 类 哈希和 ...

我可以调试并解决问题并与您分享解决方案

无处可寻

这行代码出现错误异常

if(strpos($utf8 , $this->addressPrefixByte) !== 0) return false; // strpos(): Non-string needles will be interpreted as strings in the future. Use an explicit chr() call to preserve the current behavior

这个问题是因为 PHP 7.3 的错误并用 PHP 7.2 ( Exception: stripos(): Non-string needles will be interpreted as strings in the future. Use an explicit chr() call to preserve the current behavior #770 )

修复

并解决差异

在密钥对数组中，我从 Private Key Hex 的第一个中删除 0x 然后我可以访问 Tron 中的钱包 Link Extension don记得要有激活钱包的过渡
