Remarks

AES 128 bit PDF security is compatible with PDF version 1.5 and higher and can be read with Adobe Acrobat Reader version 7 or higher. Older readers will not be able to read document encrypted with this security. Setting document version to lower values will throw an exception at the time of draw. For more details on AES 128 bit security take a look at the Security topic.
