|PDF Security and Digital Signature|
The PDF security settings change the viewing, extracting, printing, and form filling permissions of your output PDF document. You can also apply Digital Signature to your PDF which identifies you as the author of the document pretty much same as the conventional handwritten signature does.
Enable PDF Security
Select this option to turn PDF Security on (The security settings must be honored by the PDF viewing application in order to secure a document. Adobe Acrobat® as well as other PDF related products from BCL Technologies honor PDF security.)
The PDF security settings change the viewing, extracting, printing, and form filling permissions of your output PDF document. For example, de-selecting the print feature means that users will be prevented from printing your PDF document.
Two security types are available:
This option sets the Owner Password. The owner password allows the owner of the document to access various permissions from within a PDF viewing application. For example, in Adobe Acrobat®, the owner can click [File -> Document Security] and enter the owner password to change document settings.
This option sets the User Password. After the PDF is created, users must enter this password before being able to view the file.
When the security type is set to 40 bit security, there are only two options for printing:
When the security type is set to 128 bit security, there are three options for printing:
- Permit Full Printing: Allows the user to print the PDF document
- Permit Low Level Printing: Allows the user to print a low quality copy of the PDF document
- No Printing: Prevents the user from printing the PDF document
When the security type is set to 40 bit security, there are only two options for modification:

What is Digital Signature
A digital signature identifies the person signing a document pretty much same as the conventional handwritten signature does. Unlike conventional signatures, however, a digital signature also stores information about the person signing the document. Signatures also help prevent unwanted changes to a PDF document.
easyPDF Printer supports two kinds of signatures: visible and invisible signatures. A visible signature appears both in the document and the Signature tab. An invisible signature only appears in the Signatures tab. A document is best signed only after you have applied the final changes to it, so it doesn't have to be altered anymore.
Select or Create a Digital ID
To apply Digital Signature into your PDF document, you must first select the Digital ID that you would like to use to sign the PDF file. If you do not have a Digital ID, you can create a new one.
Create a new Digital ID
Click the "New" button to create a new self-signed Digital ID. You will be the owner of this Digital ID, and when you sign a PDF file using this ID, other people can verify that your signature is valid by comparing it with your certificate (you can send them your certificate before hand. See Export Certificate below for more information on how to distribute your certificate).
Click [Del] to remove the Digital ID from the easyPDF Printer Digital ID Bank. Click [View] to view the Digital ID details.
Click [View] to view the Digital ID details.
Click to import a certificate from a file on disk.
A Certificate, which is issued by a certification authority, is a confirmation of your identity and contains information used to protect data or to establish secure network connections. A certificate store is the system area where certificates are kept.
File to Import
Specify the file you want to import. You will need password to move forward.
Note: More than one certificate can be stored in a single file in the following format:
You can export either your Certificate or your Digital ID.
When you attach your digital signature to a PDF file, anyone who needs to verify that you signed the document must have a copy of your certificate. To export your certificate, click [Export] and select [Certificate]. Please note that people can also obtain a copy of your certificate by choosing to trust a document that you have signed. However, physically giving them a *.cer file that they can install and trust is a better practice.
Export Digital ID
You may need to export a copy of your Digital ID file (e.g. giving someone else the power to sign documents on your behalf). To export your Digital ID, click [Export] and select [Digital ID]. Please note that this file is encrypted and, and you must enter your password to sign a document with this Digital ID.
You can change the signature details associated with a particular PDF file such as "Reason for Signing", "Contact Information," and "Location". This information will be included with your signature.
If you would like your signature to appear as a graphic on the first page of the PDF file, select the [Visible] checkbox. You can then set the size of the graphic by changing the width and height percentages. You can then click anywhere inside the "position box" to choose the coordinates where the graphic should appear.
