Check if PDF is password protected

Hello,

Is there a way to check if a PDF is password protected, other than calling Document.Open() and checking the return value? I would like to be able to check if the PDF is password protected without actually opening it if it's not.

Thanks,
Andrew

Hi,
sorry fo the delay.

Yes try to use : For more info check this .

Document.IsEncrypted() can only be called after a Document has been opened. I would like a way to check if a PDF is password protected without actually opening it. Such as a static method:

Also, just for clarification, is "encryption" the same thing as password protection?

Hi,
yes they are the same thing.

About the static method, we are evaluating to make a method that returns if the pdf isEncypted or not, but even in this method we have to open the pdf, check if is encrypted and return (same operation you do now).
