@johnson.velusamy,
Thanks for contacting support.
Both Aspose.Pdf for .NET and Aspose.Words for .NET use GDI or GDI+ during documents creation as well as manipulation.
Aspose.Pdf for .NET uses System.Drawing and Aspose.Words do not mainly use this namesapce.

Does it store any passwords such as user credentials?
[/quote]The password is not stored within the documents. It is only used to encrypt or decrypt the document. The password itself is not stored but string computed on the base of password which is stored as hash and not stored in open format.

Does it communicate with the internet to perform its function.
[/quote]The internet connection is used for installation of API packages and for further manipulation, they do not require internet connection.
