Sign PDF with Timestamp from Timestamp Server Authority (TSA) with Limagito File Mover version 2023

In this example we are going to a sign a PDF that is both long-term validation (LTV) enabled and includes a validating timestamp from a Timestamp Server Authority (TSA).

• As source we are going to use a Windows folder [WIN]:

• Be sure to only allow .pdf files. Please set the Include Filename Filter:

• Add ‘SIGN’ as Destination

• Setup ‘SIGN’ as Destination. The default setup has 5 ‘actions’:

• Select the first Action ‘Load PDF to be signed’ and an extra tab will appear in the top menu bar. Select this ‘Pdf Load’ tab.

The default setup here is %SFP%SFN which translates to Source File Path and Source File Name. So in most cases you don’t need to change this.

• Back to the ‘Setup’ tab and select ‘Options for PDF signing’ in the Action list and next ‘Pdf Options’ Tab.

1. Enable ‘Set Signing Certifcate V2 attribute’ (is enabled by default)
2. Enable ‘Set Signing Time attribute’ (is enabled by default)
3. Enable ‘Set Long-Term Validation (LTV Enabled)’
4. Enable ‘Request timestamp froma TSA server’ (Timestamp Server Authority)
5. Set the URL of the Timestamp server. We used:  http://timestamp.digicert.com
6. Enable ‘Request TSA server to include its certificate in the timestamp response’
   • Ask the timestamp server to include its certificate in the timestamp token

• Back to the ‘Setup’ tab and select ‘Appearance of the PDF signature’ in the Action list and ‘Pdf Signature’ Tab.

We used the ‘Image options’ to add a green check mark at the left side of the signature. We have a couple of built-in graphics available but also a custom JPG is possible.

• Back to the ‘Setup’ tab and select ‘Load certificate for PDF signing’ in the Action list and ‘Pdf Certificate’ Tab.

We are using a .pfx file which is a combined certificate and private key file type.

• Back to the ‘Setup’ tab and select ‘Sign and save the PDF’ in the Action list and ‘Pdf Signing’ Tab.

• Next we enabled the Rule and triggered it manually:

• Result of the RunTime Log:

• Signed PDF result:

We have added quite some options already but we are open to new ideas. Please let us know if you need any help.
