How to create scriptPubKey for P2PKH

1. Get public key hash

Get the public key hash by computing OP_HASH160 of public key

In this example:

  • public key: 033e8c5dcb8e35670de496b57c1fa4366800ce3be5fded9b8800759881bc8da2e5
  • public key hash: 60d47ac02b129c08f94232ea506d1826424fe7be
> export PUB_KEY_HASH=60d47ac02b129c08f94232ea506d1826424fe7be

2. Create script

Script

OP_DUP OP_HASH160 <pubKeyHash> OP_EQUALVERIFY OP_CHECKSIG

OP_DUP OP_HASH160 bytes to push pubKeyHash OP_EQUALVERIFY OP_CHECKSIG
76 a9 14 60d47a... 88 ac
Output
> echo 76a914${PUB_KEY_HASH}88ac
76a91460d47ac02b129c08f94232ea506d1826424fe7be88ac

3. Verify (Optional)

In bitcoin-qt debug console

> decodescript 76a91460d47ac02b129c08f94232ea506d1826424fe7be88ac
{
  "asm": "OP_DUP OP_HASH160 60d47ac02b129c08f94232ea506d1826424fe7be OP_EQUALVERIFY OP_CHECKSIG",
  ...
}
