Public Sub New (fileName As String, password As String)

参数

fileName
String

PKCS7 签名文件的名称。

password
String

访问 X.509 证书数据所需的密码。

属性

例外

发生了与证书有关的错误。 例如:

  • 证书文件不存在。

  • 证书无效。

  • 证书的密码不正确。

fileName 参数为 null

注解

ASN.1 DER 是此类支持的唯一证书格式。 使用正确的密码调用此构造函数会解密私钥并将其保存到密钥容器。

如果通过为 fileName指定 PKCS7 签名文件存储来创建X509Certificate证书,X509Certificate则会为签名存储的证书而不是存储区中的任何证书创建 。
