PDF Digital Signature with BTP SAP Forms Service by Adobe and Test with Postman

In my blog Configure the SAP BTP Cloud Foundry Environment Subaccount with SAP Forms Service by Adobe and Test with Postman, we can render a pdf document with BTP ADS(SAP Forms Service by Adobe).  Some customers need to use interactive PDF form and need use digital signature for filled  interactive PDF form.   If you require additional document security such as certification or digital signatures, you can obtain other credentials from a Certificate Authority (CA). You install and configure other credentials the same way that you install the Adobe Reader Rights certificate.  But for testing purpose I will use self signed certificate . I will demo the testing steps as the following.

Step 1 prepare selfsigned certificate in format P12 by using openssl .

Step 2 upload p12 file and create server credential .

Step 3 adjust the xdp file to make the text field user enter and add signature field by using sap adobe livecycle designer.

Step 4 create form and upload template in Step 3 in Ads as

step 5 in blog

Step 5 render pdf as interactive form as step 6 in blog , but we need to change the form type as interactive

Step 6  sign the pdf document from step 5 .

Step 7 get signature base on signed pdf document .

The end.

Thank you for your time!

Best regards!
