    Validate Expired Digital Signature

    DKinsley Level 1

      We are a small to medium sized business and have our employee's public keys in a shared network read-only folder. We are using self-signed digital signatures created in Acrobat 9 and X.


      My understanding is that the digital signatures expire after 5 years.

      1. How do we validate a document that was signed but now that digital signature has expired?
      2. Do we need to keep all the public keys including the old expired and newly created versions?
      3. Aren't the file names the same? How do we keep them in the same folder with identical filenames?
