パラメーター

名前	型	方向	説明
dwCertEncodingType	CERT_QUERY_ENCODING_TYPE	in	エンコード種別。通常はX509_ASN_ENCODINGを指定する。
pszPubKeyOID	LPCSTR	inoptional	公開鍵アルゴリズムのOID文字列。NULLで既定のRSAが使われる。
pPubKeyStruc	PUBLICKEYSTRUC*	in	CSP形式の公開鍵BLOB先頭にあるPUBLICKEYSTRUCヘッダーへのポインター。
cbPubKeyStruc	DWORD	in	pPubKeyStrucが指す公開鍵BLOB全体のサイズ(バイト単位)。
dwFlags	DWORD	in	予約フラグ。通常は0を指定する。
pvReserved	void*	optional	予約パラメーター。NULLを指定する。
pbHash	BYTE*	outoptional	生成された鍵識別子(ハッシュ)を受け取るバッファー。サイズ取得時はNULL可。
pcbHash	DWORD*	inout	入力時はバッファーサイズ、出力時は実際のハッシュ長(バイト)を受け渡すポインター。
