Project description:
"The proposed project concerns the development of a desktop application that enables end users to apply qualified digital signatures and secure timestamps to one or more PDF documents.
The application will be installed locally on the user’s computer, and its use will be controlled through a per-machine licensing mechanism. In practice, this means that each license will be strictly bound to a single workstation, and the software will not be installable or activatable on more than one device under the same license.
Functionally, the application should provide the following capabilities:
Allow the user to select one or multiple PDF files and apply a digital signature and secure timestamp to each selected file.
In the case where the user signs a single PDF document, offer the possibility to add a visible signature block, configurable by the user, including:
custom text (e.g. name, role, signing reason, date, etc.),
one or more images (e.g. scanned handwritten signature, logo),
and the ability to define the position and size of the visible signature field on the page.
Use a hardware token (connected and installed on the user’s computer) to perform the digital signing operation. The token will contain the user’s public and private key certificates, which the application must access securely in order to create the digital signature in accordance with relevant standards.
Attach a secure timestamp to each signed PDF, obtained from an appropriate Time Stamping Authority (TSA), so that the signature is both cryptographically valid and time-anchored." (client-provided description)
