證書的密碼不正確。

備註

此建構器利用位元組陣列和密碼建立一個新 X509Certificate2 物件，該密碼是存取憑證資料所需的。它與包含憑證私鑰的 PKCS12（PFX）檔案一起使用。用正確密碼呼叫此構造子，解密私鑰並將其儲存到金鑰容器中。

Important

千萬不要在原始碼裡硬寫密碼。硬編碼密碼可透過 Ildasm.exe（IL 反組譯器）、十六進位編輯器，或直接在文字編輯器如 Notepad.exe中開啟組合語言擷取。

如果你透過指定一個 PKCS7 簽署的檔案儲存X509Certificate2庫來建立rawData憑證，則X509Certificate2是為簽署儲存庫的憑證建立，而非儲存庫內的任何憑證。

Loading certificate data through the constructor or Import is obsolete. Use X509CertificateLoader instead to load certificates.

參數

fileName: String

一個憑證檔案的名稱。

password: String

存取 X.509 憑證資料所需的密碼。

keyStorageFlags: X509KeyStorageFlags

這是一組位元組合的列舉值，控制憑證的匯入地點與方式。

屬性: ObsoleteAttribute UnsupportedOSPlatformAttribute

例外狀況

CryptographicException

憑證出錯了。例如：

該憑證檔案不存在。
憑證無效。
證書的密碼不正確。
