パラメーター

名前	型	方向	説明
pSubjectInfo	SIP_SUBJECTINFO*	in	対象データを識別するSIP_SUBJECTINFO構造体へのポインタ。署名対象の情報を保持する。
pSig	BYTE*	inoptional	シールされた署名データを格納したバッファへのポインタ。
dwSig	DWORD	in	pSigが指す署名データのバイト数。
pbDigest	BYTE*	outoptional	計算されたシールドダイジェストを受け取るバッファへのポインタ。NULLでサイズ照会可能。
pcbDigest	DWORD*	inout	pbDigestバッファのサイズ(バイト)を入出力するポインタ。出力時に実際のダイジェスト長が返る。
