获取 Microsoft Office Word 在用密码对文档加密时使用的算法加密提供程序的名称。
public string PasswordEncryptionProvider { get; }属性值
Microsoft Office Word 在用密码对文档加密时使用的算法加密提供程序的名称。
示例
如果使用的密码加密算法不是 "Microsoft RSA SChannel 加密提供程序"，则下面的代码示例将设置密码加密选项。 若要使用此示例，请在 ThisDocument 文档级项目的类中运行它。
private void DocumentPasswordEncryptionProvider()
{
if (this.PasswordEncryptionProvider != "Microsoft RSA SChannel Cryptographic Provider")
{
string PasswordEncryptionProvider = "Microsoft RSA SChannel Cryptographic Provider";
string PasswordEncryptionAlgorithm = "RC4";
int PasswordEncryptionKeyLength = 56;
object PasswordEncryptionFileProperties = true;
this.SetPasswordEncryptionOptions(PasswordEncryptionProvider,
PasswordEncryptionAlgorithm, PasswordEncryptionKeyLength,
ref PasswordEncryptionFileProperties);
}
}
Private Sub DocumentPasswordEncryptionProvider()
If Me.PasswordEncryptionProvider <> "Microsoft RSA SChannel Cryptographic Provider" Then
Dim PasswordEncryptionProvider As String = _
"Microsoft RSA SChannel Cryptographic Provider"
Dim PasswordEncryptionAlgorithm As String = "RC4"
Dim PasswordEncryptionKeyLength As Integer = 56
Dim PasswordEncryptionFileProperties As Object = True
Me.SetPasswordEncryptionOptions(PasswordEncryptionProvider, _
PasswordEncryptionAlgorithm, PasswordEncryptionKeyLength, _
PasswordEncryptionFileProperties)
End If
End Sub
注解
使用 SetPasswordEncryptionOptions 方法可指定在用密码对文档加密时，Word 使用的算法加密提供程序的名称。
