Overview of the sample

The Add Signature Validation Info sample automates the addition of validation-related information to the signed or certified PDF documents using Digital Signatures.

The process is triggered when a PDF document is placed in a watched folder.

Click the Gear icon on the Creative Cloud Desktop application and select the Quit option. Navigate to the /Library folder. If you don't see this under the Go menu on a Finder window, hold down the Option key and it will appear. Navigate to Application Support - Adobe. Find the OOBE folder and open it.

The process checks whether the PDF document contains a signature. If it does, it continues to validate the signature. If the signature is valid, the validation-related information for that signature is added to the PDF document. Output is then written to a folder holding validated documents. If, the signature is not valid or if any exceptions happened during the validation process, the document is not updated. The unchanged document is stored in a folder holding invalid documents.

Solution Components used:

  • SignatureService
  • Get Signature Field List: Returns a list of all the signaturefields located within a PDF document. You can retrieve the names of all the signaturefields in a PDF document for signing or certifying.
  • Add Signature Validation Info: Adds signaturevalidationinformation for long-term validation of digital signatures applied to a PDF document.

Configuring the sample

Configure certificate

For

In the following steps, you need three certificate files: DSSTSCA.cer, Perf_ValidcrlICA.cer, and PerfCA.cer. They are located at the subfolder Resources of folder collateral within the ZIP file Adobe-Samples-Service-DigitalSignatures.zip.

  1. Log in to Administration Console (http://[hostname]:[port]/adminui).
  2. Click Home > Settings > Trust Store Management > Certificates.
  3. Click Import and on the Import Credential page specify this information:
    - Trust Store Type: enable all the Trust Anchors except Trust for SSL connections

    - Alias: Perf_Validcrl
    - Credential: Perf_ValidcrlICA.cer
  8. Click OK to import the certificate.

Running the sample

  1. Open the collateral folder within the downloaded ZIP file, Adobe-Samples-Service-DigitalSignatures.zip. Expand the subfolder Input, drop the Input_file.pdf file into the watched folder, C:tmpLCSamplesWatchedFolderDigitalSignaturesAddSignatureValidationInfoinput on Windows, /tmp/LCSamples/WatchedFolder/DigitalSignatures/AddSignatureValidationInfo/input on Unix.
  2. The output PDF file is written out to C:tmpLCSamplesOutputDigitalSignaturesAddSignatureValidationInfoValid on Windows or /tmp/LCSamples/Output/DigitalSignatures/AddSignatureValidationInfo/Valid on Unix. Verify that the signature is added:
    - Open the output PDF document using Acrobat.
    - Select Advanced > Preflight
    - In the Preflight dialog box, click Options on the upper-right corner.
    - Select Browse Internal PDF structure.
    - Click the Browse internal document structure icon at the upper left of the dialog box showed in the following figure.
    - Expand The document root Catalog. Notice a 'DSS' directory is created at the time of validation.

    Note: The 'Preflight' selection can be found in the Acrobat X (View -> Tools -> Print Production -> Preflight).
  3. Open the collateral folder within the downloaded ZIP file Adobe-Samples-Service-DigitalSignatures.zip again. Expand the subfolder Input, drop the Input_file_NotSigned.pdf file into the input subfolder of the watched folder C:tmpLCSamplesWatchedFolderDigitalSignaturesAddSignatureValidationInfoinput on Windows, /tmp/LCSamples/WatchedFolder/DigitalSignatures/AddSignatureValidationInfo/input on Unix.
  4. The output PDF file is written out to C:tmpLCSamplesOutputDigitalSignaturesAddSignatureValidationInfoInvalid on Windows or /tmp/LCSamples/Output/DigitalSignatures/AddSignatureValidationInfo/Invalid on Unix. The Invalid folder (as specified in the step 'Configure watched folder'). Notice that the PDF file is the same as the input PDF file. The input PDF file has not been signed, therefore signature validation information cannot be added.
