GetScriptForMultisig()

CScript GetScriptForMultisig	(	int	nRequired,
		const std::vector< CPubKey > &	keys
	)

Generate a multisig script.

GetScriptForRawPubKey()

CScript GetScriptForRawPubKey

(

const CPubKey &

pubkey

)

Generate a P2PK script for the given pubkey.

Get the name of a TxoutType as a string.

MatchMultiA()

std::optional< std::pair< int, std::vector< Span< const unsigned char > > > > MatchMultiA

(

const CScript &script

LIFETIMEBOUND

)

Determine if script is a "multi_a" script.

Returns (threshold, keyspans) if so, and nullopt otherwise. The keyspans refer to bytes in the passed script.

Solver()

TxoutType Solver	(	const CScript &	scriptPubKey,
		std::vector< std::vector< unsigned char > > &	vSolutionsRet
	)

Parse a scriptPubKey and identify script type for standard scripts.

If successful, returns script type and parsed pubkeys or hashes, depending on the type. For example, for a P2SH script, vSolutionsRet will contain the script hash, for P2PKH it will contain the key hash, etc.

Parameters

[in]	scriptPubKey	Script to parse
[out]	vSolutionsRet	Vector of parsed pubkeys and hashes

Returns

The script type. TxoutType::NONSTANDARD represents a failed solve.
