Issue in encrypted PDF file

[Satyanand@adobeforums.com]

I had encrypted one PDF file using VC++ component.
But when i open the encrypted file in Adobe Professional it asks for saving the file.

Password for encrypted file is : "a"

1) File which is encrypted(Original File)
<http://www.2shared.com/file/4686154/673db65f/blank.html>
2) Encrypted File Using VC++ component
<http://www.2shared.com/file/4686152/8e5e136a/Unsaved_Encr.html>
if opened in adobe professional it asks to save, when we try to close the PDF.

3) Following link is for file which i had opened in Adobe Professional, and choose to save when it asks for saving.

Can anyone please help me, why the encrypted file asks to save, when opened in Adobe professional.
Also when i choose to save the file after opening it in Adobe professional, why it changes whole structure of my encrypted file.

Thanks.

Probably because the PDF is invalid/broken.

Thanks Leonard,
Is it possible for you to tell me why PDF is invalid or broken.
OR what wrong thing done by me that broken the PDF.

Thanks Again.
