    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",
  ...
}
