Namespace: Microsoft.Office.Tools.Word
Assembly: Microsoft.Office.Tools.Word.v4.0.Utilities (in Microsoft.Office.Tools.Word.v4.0.Utilities.dll)
Syntax
'Declaration
Public ReadOnly Property PasswordEncryptionProvider As String
public string PasswordEncryptionProvider { get; }
Property Value
Type: System.String
The name of the algorithm encryption provider that Microsoft Office Word uses when encrypting documents with passwords.
Remarks
Use the SetPasswordEncryptionOptions method to specify the name of the algorithm encryption provider that Word uses when encrypting documents with passwords.
Examples
The following code example sets the password encryption options if the password encryption algorithm in use is not "Microsoft RSA SChannel Cryptographic Provider." To use this example, run it from the ThisDocument class in a document-level project.
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
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);
}
