    “I have a PDF file in which I should add my digital signature certified via Adobe Reader. When I go to add the signature though, all the signature options are greyed out. I checked the security systems and signatures are allowed…. I'm using the latest version of Adobe but I can't ... Any advice? "

    Actually, Adobe Reader is just a PDF document reader. To add a digital signature (with certificate) in a PDF file, and especially in an externally imported PDF document, you need a professional PDF program such as PDF Element Editor. Although such a program is not as famous and popular as Adobe Reader and Adobe Acrobat, it is capable of applying a digital signature certified which will allow you to speed up your workflow with colleagues, customers and partners. Below we see how to use this program for insert a certified digital signature in a PDF file.

After the download, if there is a message asking you to run the application, click Run and proceed with the installation.

    Step 2. Create digital signature in PDF

    Click on Open File ... to browse your computer and search for the PDF document to import into the program and on which you want to insert the certified signature. After opening, access the section "Protect ”To proceed with the creation and addition of the certified digital signature in the PDF.



    In the "protect" menu, click on "Signature document". Move the mouse over the PDF document and click to draw the area where you want to insert the signature. When you do this, a window called "Add Digital ID".

    Users who want to insert the signature in the PDF through this program for the first time, have to click on the button "New digital ID”To create a new code. In the "Existing digital ID" box, you can import the certificate, if you already have it.
    If you don't have a digital ID, create one by entering your name, email address, company name, etc ...

    NB: Given theauthenticity of the digital signature you will be able to sign PDF documents using a certificate-based digital ID, just like the one created by this PDF Editor program. Alternatively, a certificate ID issued by an external and trusted certification authority can also be imported into the program. With a certified digital signature, recipients will be able to verify the authenticity or otherwise of the PDF file.

    If instead of a certified digital signature, you want to insert your own "handwritten" signature, read this article.

     

     

    Does the signature digitally inserted with this program then have the value of "authenticity" of the PDF document?
