How get the public key to hex script? like command decodescript of bitcoin core

Question

If I want to recreate the command decodescript of bitcoin core? how is the process for decode the script P2PK?

So I'm writing for personal exercise the Bitcoin script decompiler, form moment I have a version alpha of the process decodifier of the script P2PK script.

In my example, I get the scriptPubKey of the codebase block, so the data are

The hex of the script: 4104678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef38c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5fac

So the decoded script is

04678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef38c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5fac OP_CHECKSIG

The result of the command decodescript of bitcoin core

{
  "asm": "04678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef38c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5f OP_CHECKSIG",
  "reqSigs": 1,
  "type": "pubkey",
  "addresses": [
    "1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa"
  ],
  "p2sh": "3DjjKyU38gSfuVxajV43MUy4vHkg1JVL7T"
}

So the my process decode is

1. I get the type of transaction with this code

   string hex(argv[1]);
   BitcoinOPCode bitcoinOpCode;
   
   string opcode = hex.substr(0, 2);
   int32_t optValue = std::stoul(opcode, nullptr, 16);
   auto optMap = bitcoinOpCode.opCodeList.find(optValue);
   string optCode = optMap->second;
   //Not are all type script
   if (optCode == "OP_HASH160") {
       cout << "Finded the P2SHA";
   } else if (optCode == "OP_DUP") {
       cout << "Finded the P2PKH";
   } else {
       cout << "Finded the old style script\n";
   }
   

---

2. The script is a script old style so I decode the hex script with this code

   string key = hex.substr(2, optValue * 2);
   opcode = hex.substr(2 + optValue * 2, hex.length());
   cout << "Hex key is: " << key << " op code: " << opcode << endl;
   optValue = std::stoul(opcode, nullptr, 16);
   optMap = bitcoinOpCode.opCodeList.find(optValue);
   opcode = optMap->second;
   

The result is 04678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef38c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5f OP_CHECKSIG

3. Find the key to this hex string 04678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef38c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5f

I try with this code

Bytes bytes = hexBytes(key.c_str());

 //Ripemd160
 uint8_t result[Ripemd160::HASH_LEN];
 Ripemd160::getHash(bytes.data(), key.length(), result);
 char address[36];
 Base58Check::pubkeyHashToBase58Check(result, 0x00, address);
 cout << "The script public key is: " << address  << " " << opcode << endl;

But the result is wrong 1NXtFSm6h4QAVBQ7ezaDc3ZvSKFj9GTfoV

I looked the code bitcoin, so I think the bitcoin core decode the script with this code GetScriptForDestination(WitnessV0KeyHash(Hash160(solutions_data[0].begin(), solutions_data[0].end())));

but in the my logic exist an bug, can you help me to find it? thanks
