SignStep()

static bool SignStep ( const BaseSignatureCreator &  creator, const CScript &  scriptPubKey, CScript &  scriptSigRet, txnouttype &  whichTypeRet  )

static

Sign scriptPubKey using signature made with creator. Signatures are returned in scriptSigRet (or returns false if scriptPubKey can't be signed), unless whichTypeRet is TX_SCRIPTHASH, in which case scriptSigRet is the redemption script. Returns false if scriptPubKey could not be completely satisfied.
