Issues with PDFFileInfo in checking Encrypted- password Protected Files

Aspose.PDF Product Family

Hi,

I am using the below code for checking encrypted and password protected files. For encrypted files isPDFFile always return fals and isEncrypted throws an error:

PdfFileInfo is not initialized. Use constructors with parameters or properties for initialization.

It always sets tru for hasOpenPassword no matter what and always throws an invalid passwordexception for editPassword even if it the one of the region of the files are protected.

Is there a way to capture all these information for a pdf file.

if(fileInfo.isPdfFile()){
metaData.setMimeType(PDFMetadata.MIME_TYPE_PDF);
}

//File is Password protected for opening.
if(fileInfo.hasOpenPassword()){
metaData.setPasswordProtected(true);
}

//File is Password Protected for Editing.
if(fileInfo.hasEditPassword()){
metaData.setSecure(true);
}

//File is encrypted.
if(fileInfo.isEncrypted()){
metaData.setEncrypted(true);
}

Regards,

Hi Rajeev,

Thanks for contacting support.

I have tested the scenario using one of my sample PDF files, and as per my observations, the correct password encryption information is being returned. Please take a look at the following code snippet which I have used for testing purposes. Can you please share your input/source PDF file, so that we can test the scenario in our environment. We are sorry for this inconvenience.

Java

// instantiate FileInfo object
com.aspose.pdf.facades.PdfFileInfo fileInfo = new com.aspose.pdf.facades.PdfFileInfo();

// bind source PDF file
fileInfo.bindPdf("c:/pdftest/table_Secured_output.pdf");

// print if source file is password encrypted
System.out.println("Is document encrypted = " + fileInfo.isEncrypted());

// determine if the password type for document is User
if (fileInfo.getPasswordType() == com.aspose.pdf.PasswordType.User) {
    // print password type information
    System.out.println("Password type = " + fileInfo.getPasswordType() + " (type = User)");
}

fileInfo = new com.aspose.pdf.facades.PdfFileInfo();
fileInfo.bindPdf("c:/pdftest/table_Secured_output.pdf", "user");

// print if document is encrypted
System.out.println("Document is encrypted = " + fileInfo.isEncrypted());

// determine if the password type for document is Owner
if (fileInfo.getPasswordType() == com.aspose.pdf.PasswordType.Owner) {
    // print password type information
    System.out.println("Password type = " + fileInfo.getPasswordType() + " (type = Owner)");
}

// print if document has open password specified
System.out.println("Document has Open Password = " + fileInfo.hasOpenPassword());
// print if document has edit password specified
System.out.println("Document has Edit Password = " + fileInfo.hasEditPassword());

fileInfo = new com.aspose.pdf.facades.PdfFileInfo();
fileInfo.bindPdf("c:/pdftest/table_Secured_output.pdf");

// print if document is encrypted
System.out.println("Document is encrypted = " + fileInfo.isEncrypted());

if (fileInfo.getPasswordType() == com.aspose.pdf.PasswordType.Inaccessible) {
    // print password type information
    System.out.println("Password type = " + fileInfo.getPasswordType() + " (type = Inaccessible)");
}

if (fileInfo.hasOpenPassword()) {
    // Document has open password enable
    System.out.println("Document has open password enabled = " + fileInfo.hasOpenPassword());
}

try {
    boolean hasOwnerPassword = fileInfo.hasEditPassword();
    System.out.println("When PasswordType is Inaccessible we can't read HasEditPassword property.");
} catch (Exception e) {
    // write what we expect
}
