How to Export and Import Digital Signature

I apologize if this is solved somewhere else but I cannot find the answer.  

 

I searched and found this thread: How to export signatures and preferences - Adobe Support Community - 5155363

 

Also this thread: Export/Import Digital Signature - Adobe Support Community - 11002921

 

Neither were helpful in solving the issue.

 

I have Adobe Acrobat DC on my Windows computer. I setup a digital signature there and want to copy it to my Acrobat Pro DC on my Macintosh laptop. I'm using version 2021.007.20091 on the Macintosh PC and 2021.007.20091 also on my Windows PC.

 

On the Windows PC, I created a digital signature that includes an image of my actual signature.  I use this regularly to sign invoices and other forms.

Based on instructions, I can select the signature and export it to a file on my Windows PC.  I get a .fdf file.  I emailed the file to my Macintosh laptop and saved it to the /Documents directory.  However, I see no method for importing it.  Am I missign something?

    You have exported the public key of the digital id.

    To import the public key open the fdf file in Acrobat.

    Then you can validate signed documents on the Mac.

      Of course, though, you cannot sign with a public key - otherwise anyone could make a signature as you. The purpose of exporting the public key is to allow a signature to be validated by anyone.

        Okay, thank you. I think I have it.  I imported the file as a .fdf file.  

         

         

        This allows me to "sign" a document and have the "signature" listed as valid on the Macintosh.  It doesn't show my signature image like on the signature form, but it will work.

          Seems like when you browse for the certificate file with Acrobat it doesn't support the FDF file format nor the .cer file format and neither the PKCS#7 file format.

           

          It only supports .p12  or .pfx (Personal Information Exchange) files. 

           

          Try PKCS#7 when exporting, and use a file converter.

           

          I've seen in other forums outside of Adobe's some users recommend tools like SSL Converter, for example.

           

          And in some Micrososft support forums CryptoAPI, Pvk2Pfx, MakeCert, CertMgr to name a few.
