Remarks

AES 256 bit PDF security is compatible with PDF version 1.5 and higher. This class is FIPS compliant when used in applications that targets .NET Framework 3.5 and higher. Setting document’s PDF version to 1.4 or lower will throw an exception during the creation of PDF. Adobe Acrobat Reader version X or higher is needed to open documents encrypted with this class.
