DocumentBase.PasswordEncryptionAlgorithm 属性
获取 Microsoft Office Word 在用密码对文档加密时使用的算法。
命名空间: Microsoft.Office.Tools.Word
程序集: Microsoft.Office.Tools.Word.v4.0.Utilities(在 Microsoft.Office.Tools.Word.v4.0.Utilities.dll 中)
语法
声明
Public ReadOnly Property PasswordEncryptionAlgorithm As String
public string PasswordEncryptionAlgorithm { get; }
属性值
类型:System.String
Microsoft Office Word 在用密码对文档加密时使用的算法。
备注
使用 SetPasswordEncryptionOptions 方法指定 Word 在用密码对文档加密时使用的算法。
示例
下面的代码示例在使用的密码加密算法为“OfficeXor”时将密码加密设置为更强的加密。 若要使用此示例,请从文档级项目内的 ThisDocument 类中运行此示例。
Private Sub DocumentPasswordEncryptionAlgorithm()
If Me.PasswordEncryptionAlgorithm = "OfficeXor" 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
private void DocumentPasswordEncryptionAlgorithm()
{
if (this.PasswordEncryptionAlgorithm == "OfficeXor")
{
string PasswordEncryptionProvider = "Microsoft RSA SChannel Cryptographic Provider";
string PasswordEncryptionAlgorithm ="RC4";
int PasswordEncryptionKeyLength = 56;
object PasswordEncryptionFileProperties = true;
this.SetPasswordEncryptionOptions(PasswordEncryptionProvider,
PasswordEncryptionAlgorithm, PasswordEncryptionKeyLength,
ref PasswordEncryptionFileProperties);
}
}
