Create a digital ID for PDF

A digital ID contains signature information that is either created by you (known as a self-sign digital ID), or provided by a third party. A digital ID provided by a third party will include a certificate, which serves to confirm your signature information and help to secure your document.

When you sign a document -- physically or digitally -- you are indicating that you:

1. Approve the document's contents.
2. Are someone who has the right to certify that document.

Digital IDs provided by 3rd parties are considered more secure, because an independent certificate authority has ratified them. Think of it like this: a signature applied using a self-sign signature tells a document consumer that "This document is valid, and I am authorized to sign this document," while a signature applied using a 3rd party digital ID tells them that "Not only is this document valid, I am authorized."

Creating your first digital ID

Before you can take advantage of all the options for using digital IDs, certifying documents, adding appearance settings, etc., you must create at least one personal digital ID.

To create a self-sign digital ID:

1. Select Document > Self-Sign Security > My Digital ID Files > Select My Digital ID File.
2. In the Self-Sign Security Log In window, click the New User Profile button.
3. Fill in your details: name, organization, country, password, confirm password, etc., and then click OK.
4. Enter a name for your ID in the File Name field and save your ID to your computer. By default, the name used in the Name field in the Create New User window appears in the File name field. If this works for you, just click Save without renaming the file.
5. Your ID is now ready for use in Nitro PDF Professional for signing and certifying PDF documents.

Importing IDs

If you have an ID created from another PDF authoring tool, such as Adobe^® Acrobat^®, you can import existing IDs and make them available in Nitro PDF Professional.

To import a digital ID:

1. Select Document > Self-Sign Security > My Digital ID and click Add.
2. Select the Import Digital ID File  button.
3. Browse through to the appropriate digital ID file and select Open.
4. Enter the password and click OK.
5. Close the Manage My Digital IDs window to finish
