◆ 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.

std::string GetTxnOutputType ( TxoutType  t)

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]scriptPubKeyScript to parse
[out]vSolutionsRetVector of parsed pubkeys and hashes
Returns
The script type. TxoutType::NONSTANDARD represents a failed solve.
