Thanks much

Up to the 7.xx-versions of QuickPDF you could use SecurityInfo after LoadFromFile to check for user- and masterpassword.
Debenu decided then to be completely legal to the pdf-specs.
This means that a user-password should prevent for looking into a pdf-document.
So the LoadFromFile won't work proper if the pdf-document has a user-password.
The main-password isn't a problem - SecurityInfo will check this in a proper way.
If you want to load a pdf-document with a user-password, after LoadFromFile it's always necessary now to use LastErrorCode.
The last error code 404 shows you that there's a user password.
I've comunicated about this issue with Debenu in the past.

How did you open in QPDF it if it had a password?   You can simply call DAOpenFileReadOnly with an empty password.  If the file has a password you should get a zero result and the last error code should be 404.  But it depends what type of functionality the password you are checking for would be protecting.]]> Sat, 19 Mar 2016 09:17:36 +0000 http://www.quickpdf.org/forum/securityinfo_topic3285_post13076.html#13076 <![CDATA[SecurityInfo : I am trying to discover if a PDF...]]> http://www.quickpdf.org/forum/securityinfo_topic3285_post13075.html#13075 Author: mdgodfrey

I am trying to discover if a PDF has a password or not before attempting to decrypt it.
I have tried using SecurityInfo(1) and SecurityInfo(2) which checks for Master and User respectively. At least according to the documentation I have.

They both just seem to just want to return 2 which is 'No'.
I know the file has a password because I can decrypt it using the password.

So I am not sure what I am missing. Any help, please?
