bits.script.constants module

bits.script.utils module

bits.script.utils.decode_script(scriptbytes: bytes, witness: bool = False, parse: bool = False) → List[str] | Tuple[List[str] | bytes, bytes]

Decode Script. Decode witness script by using witness=True. When witness=True, you may use parse=True to parse first witness script instead of decoding.

bits.script.utils.multisig_script_pubkey(m: int, pubkeys: List[bytes]) → bytes

m-of-n multisig, n implied by length of pubkeys list :param m: int, number of signatures required :param pubkeys: list[bytes], list of pubkeys for multisig

bits.script.utils.multisig_script_sig(sigs: List[bytes]) → bytes

bits.script.utils.null_data_script_pubkey(data: bytes) → bytes

Script pubkey for Null data https://developer.bitcoin.org/devguide/transactions.html#null-data

bits.script.utils.p2pk_script_pubkey(pk: bytes) → bytes

bits.script.utils.p2pk_script_sig(sig: bytes) → bytes

bits.script.utils.p2pkh_script_pubkey(pk_hash: bytes) → bytes

bits.script.utils.p2pkh_script_sig(sig: bytes, pk: bytes)

<sig> <pubkey> :param sig: bytes, signature :param pk: bytes, public key

bits.script.utils.p2sh_multisig_script_pubkey(m: int, pubkeys: List[bytes]) → bytes

bits.script.utils.p2sh_p2wsh_script_pubkey(witness_script: bytes, witness_version: int = 0)

bits.script.utils.p2sh_p2wsh_script_sig(witness_script: bytes)

bits.script.utils.p2sh_script_pubkey(script_hash: bytes) → bytes

Parameters:

…signatures… {serialized script}

bits.script.utils.p2wpkh_script_pubkey(pk_hash: bytes, witness_version: int = 0) → bytes

native p2wpkh https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki#p2wpkh

pk_hash must be 20 bytes for v0 native p2wpkh

Ex: (v0) witness: <sig> <pubkey> scriptSig: (empty) scriptPubKey: 0 <20-byte-key-hash> (0x0014{20-byte-key-hash})

Note witness_scripthash must be 32 bytes for v0 native p2wsh

bits.script.utils.p2wsh_script_sig() → bytes

bits.script.utils.script(args: List[str], witness: bool = False) → bytes

Generic script :param args: list, script ops / data :param witness: bool, wether witness script
