Password-protected documents

GroupDocs.Parser provides the functionality to open the password-protected documents.

Here are the steps to work with password protected documents.

The following code sample shows how to process password protected documents.

    // Create an instance of Parser class with the password:
    using (Parser parser = new Parser(filePath, new LoadOptions(password)))
        // Check if text extraction is supported
        if (!parser.Features.Text)
            Console.WriteLine("Text extraction isn't supported.");
        // Print the document text
        using (TextReader reader = parser.GetText())
catch (InvalidPasswordException)
    // Print the message if the password is incorrect or empty
    Console.WriteLine("Invalid password");

If the password is incorrect or empty InvalidPasswordException exception is thrown.

The following code shows how to check whether a file is password-protected:

// Get a file info
Options.FileInfo info = Parser.GetFileInfo(document);
// Check IsEncrypted property
Console.WriteLine(info.IsEncrypted ? "Password is required" : "");
