Password-protected documents

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

The following are the steps to work with password protected documents.

• Instantiate the LoadOptions object;
• Set password in LoadOptions(String) constructor;
• Create Parser object and call any method.

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

try {
    String password = "123456";
    // Create an instance of Parser class with the password:
    try (Parser parser = new Parser(Constants.SamplePassword, new LoadOptions(password))) {
        // Check if text extraction is supported
        if (!parser.getFeatures().isText()) {
            System.out.println("Text extraction isn't supported.");
            return;
        }
        // Print the document text
        try (TextReader reader = parser.getText()) {
            System.out.println(reader.readToEnd());
        }
    }
} catch (InvalidPasswordException ex) {
    // Print the message if the password is incorrect or empty
    System.out.println("Invalid password");
}

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