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.
The following code shows how to check whether a file is password-protected:
// Get a file info
FileInfo info = Parser.getFileInfo(filePath);
// Check IsEncrypted property
System.out.println(info.isEncrypted() ? "Password is required" : "");
