Check out the “Signatures” button on the Navigation Panel to see what information is provided by Reader for signed PDF documents (e.g. Save the signed PDF form (figure 3 shows an example).In this example a certificate stored on the computer’s hard disk is used.įigure 2: This is the dialog to sign a PDF document Bring up the PDF in Reader and click on the document signature field.(If you use Adobe Acrobat instead of Adobe Reader, preview PDF in Adobe Designer can be used directly). This is necessary because the usage right to enable document signing in Adobe Reader is necessary. Render the form as an interactive PDF use for example a print program written in ABAP.Figure 1 shows what my form template looked like after this step.įigure 1: Form template with a text field and a document signature field Resize the field so that it occupies more space (to get rid of the warning).For some basic tests, I recommend not to lock form fields after signing so that you can test what it looks like if the data is modified after signing. Add a document signature field on the form.Drag and drop a text field from the standard library to the form.Form Builder in the ABAP Workbench/SAP GUI).
Let’s take a look at what this means by discussing a scenario. ADS can provide the cert chain to facilitate this but does not provide any means of this mapping built-in. Mapping of certificates to persons needs to be done in the implementation of a scenario (i.e. The signature validity can be verified by the Adobe Document Services (ADS). integrity) and if the cert used to sign can be mapped to a person or entity (authenticity). For example, data is processed in a SAP backend only if the signature is valid (i.e. To use digital signatures a so-called digital certificate is needed.
This allows you to verify the integrity of data and also authenticity of the submitter of the data.

To allow Adobe Reader to validate those certificates you will need to download and install the AOC public keys.Īnother solution is to manually add this certificate to the Adobe Trusted Certificates list, from the certificate information.Digital signatures allow you to sign a form, more precisely they allow you to sign the data entered into the form. Many public certificates, like the time stamp signature form UPF or other AOC issued certificates, have a public key encryption, and Adobe Acrobat cannot recognise them with the default settings. If Adobe Acrobat says that at least one signature have problems or signature validity is UNKNOWN, it is possible the program is not able to check its authenticity. Clicking on them you can see further details of the used certificates. Once you open the document, you can access to the Signature Board from a pop-up bar (normally blue) in the top or from the ink pen icon in the side menu and a new board will be displayed with the information of all signatures applied at that document. To validate an electronic signature with Adobe Acrobat you need to download the document in your drive and open it with this program (do not visualize the PDF within your internet browser). It is recommended to have the last updated version. Adobe Acrobat Reader DC is the most used program to read PDF documents globally.
