In the end I've written Python script to create raw TX for p2pk:
Obviously to sign the TX you need to have private key in Base58Check form already to provide while signing TX in Bitcoin Core or this UTXO in wallet.
Code:
#!/usr/bin/env python3
import sys
import struct
import json
import binascii
txid="4e9e28b2e7d9b28824ab19f02ace19dff86aed90d8fb422c640279a6fe82e0af"
vout=0
pubkey="02396543d7ab32e75c6682b4fca35c0e68f0694b0dde355de5cc2a7f8fa4affc62"
amount=0.067
tx = bytearray()
tx = tx + binascii.unhexlify('0100000001') # one input tx - last digit
txb = bytes.fromhex(txid)
seqno = 1
txb=txb[::-1]
tx = tx + bytes(txb)
tx = tx + struct.pack('
tx = tx + struct.pack('
pk = pubkey
v = amount
if len(pk) != 66:
raise ValueError("pk not 33 bytes (66 hex digits) - it has bytes: "+str(len(pk)/2))
v = int(100000000 * v)
tx = tx + struct.pack('
tx = tx + b'\x21'
tx = tx + binascii.unhexlify(pk)
tx = tx + b'\xac'
tx = tx + binascii.unhexlify('00000000')
print(binascii.hexlify(tx))
import sys
import struct
import json
import binascii
txid="4e9e28b2e7d9b28824ab19f02ace19dff86aed90d8fb422c640279a6fe82e0af"
vout=0
pubkey="02396543d7ab32e75c6682b4fca35c0e68f0694b0dde355de5cc2a7f8fa4affc62"
amount=0.067
tx = bytearray()
tx = tx + binascii.unhexlify('0100000001') # one input tx - last digit
txb = bytes.fromhex(txid)
seqno = 1
txb=txb[::-1]
tx = tx + bytes(txb)
tx = tx + struct.pack('
tx = tx + struct.pack('
pk = pubkey
v = amount
if len(pk) != 66:
raise ValueError("pk not 33 bytes (66 hex digits) - it has bytes: "+str(len(pk)/2))
v = int(100000000 * v)
tx = tx + struct.pack('
tx = tx + b'\x21'
tx = tx + binascii.unhexlify(pk)
tx = tx + b'\xac'
tx = tx + binascii.unhexlify('00000000')
print(binascii.hexlify(tx))
Obviously to sign the TX you need to have private key in Base58Check form already to provide while signing TX in Bitcoin Core or this UTXO in wallet.
Or can be done by this way,
Code:
import binascii
txid="4e9e28b2e7d9b28824ab19f02ace19dff86aed90d8fb422c640279a6fe82e0af"
vout=0
pubkey="02396543d7ab32e75c6682b4fca35c0e68f0694b0dde355de5cc2a7f8fa4affc62"
amount=0.067
tx = bytearray.fromhex(f'0100000001{txid[::-1]}{vout:08x}00{1:08x}{int(1e8*amount):016x}2321{pubkey}ac00000000')
print(binascii.hexlify(tx).decode())
txid="4e9e28b2e7d9b28824ab19f02ace19dff86aed90d8fb422c640279a6fe82e0af"
vout=0
pubkey="02396543d7ab32e75c6682b4fca35c0e68f0694b0dde355de5cc2a7f8fa4affc62"
amount=0.067
tx = bytearray.fromhex(f'0100000001{txid[::-1]}{vout:08x}00{1:08x}{int(1e8*amount):016x}2321{pubkey}ac00000000')
print(binascii.hexlify(tx).decode())
