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);
    }
}
