Digital signature
Video: How to Sign PDFs Digitally
The PDF Editor allows you to sign documents digitally and to validate any digital signature in a
document. A digital signature is used to establish the identity of the person that signed the document.
Additionally, a digital signature can be used to make sure that a signed document has not been
altered.
To sign a document:
1. On the toolbar in the Security tab, click > Add Digital Signature....
2. Select the area where you want to place the signature or simply click the desired location.
3. Select the certificate to be used from the Sign as drop-down list. To view the properties of
a certificate, select it and click Show Certificate....
If the certificate you want to use is not in the list, you will have to install it. To install a
certificate, right-click it in Windows Explorer, click Install Certificate on the shortcut menu,
and follow the instructions in the Certificate Import Wizard.
4. If required, use the Reason drop-down list to specify the reason for signing the document.
The Location and Contact fields are used to specify the location where the document was
signed and your contact information respectively.
In the Reason field, you can either select a value from the drop-down list or enter a
custom text.
5. The following can also be specified in a signature: the date and time of signing, signature
owner information, as well as the name and version number of the FineReader program that
was used.
You can also choose which information is displayed in the signature by unchecking the
names of fields that you do not want to be displayed.
If you do not want field names to be displayed in the signature, uncheck Show labels.
6. If required, click Set up Time Stamp Server and specify the server URL. If login
credentials are required to establish a connection, enter a login and a password.
7. Select the Borders and background option to add a border and a grey background to your
signature.
8. Select Add custom image to digital signature if you want your signature to include an
image. Then click the Select Image... button to browse to an image file. The image will
appear to the left of the signature.
9. Click Save and sign.
10.Save the document.
