DocumentBase.PasswordEncryptionAlgorithm 屬性
取得 Microsoft Office Word 用來以密碼加密文件的演算法。
命名空間: Microsoft.Office.Tools.Word
組件: Microsoft.Office.Tools.Word.v4.0.Utilities (在 Microsoft.Office.Tools.Word.v4.0.Utilities.dll 中)

public string PasswordEncryptionAlgorithm { get; }
屬性值
型別:System.String
Microsoft Office Word 用來以密碼加密文件的演算法。
備註
使用 SetPasswordEncryptionOptions 方法,指定 Word 用來以密碼加密文件的演算法。
範例
下列範例中,如果使用中的密碼加密演算法是 "OfficeXor",那麼程式碼會將密碼加密設為更強式的加密方法。 若要使用這個範例,請在文件層級專案中的 ThisDocument 類別執行。
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);
}
}
