3-Heights™ PDF Security Tool

PDF Tools AG

The 3-Heights™ PDF Security component offers comprehensive functionality in two independent yet combinable areas: Electronic signatures and encryption.

Electronic Signatures

Applying an electronic signature guarantees the authenticity and integrity of documents, both of which are important requirements in electronic data exchange. Depending on the characteristics of the signature and the country it is used in, an electronic signature can be equivalent to signing a document by hand. Electronic signatures offer advantages with regard to the speed, security and automation of business correspondence.

The 3-Heights™ PDF Security component is able to apply various types of electronic signature (simple, advanced and qualified). The component’s benefits include PDF/A conformity, embedding information on the validity of certificates (OCSP, CRL), time stamps and compatibility with signature hardware (HSM) for mass signature applications. The component can verify existing signatures by checking their integrity.


PDF documents used in professional circumstances contain important information that needs to be protected against unauthorized access and unintentional alteration. This is achieved by protecting PDF documents through encryption and user permission flags.

Areas of Use

Documents are signed prior to archiving; this increases compliance with audit requirements, for instance. A hardware security module can be used to handle large numbers of documents. Verification enables the authenticity and integrity of signed documents to be checked prior to archiving.

Incoming Mail:
Verification of incoming signed PDF documents to ensure they have not been modified during transmission and were transmitted by an authenticated sender.

Outgoing Mail:
The component can encrypt and apply an electronic signature to PDF documents before they are sent, thus enabling the recipient to verify authenticity and integrity.

Software Manufacturers/OEM:
The 3-Heights™ PDF Security component is quickly integrated in solutions without any need for extensive learning and programming.

Other Areas of Use:

  • Add encryption and/or digital signatures for PDF files to applications (client, server, web)
  • Centralized signature service with HSM for mass signatures in input/output management
  • Workflow support systems (author, review, release, etc.)
  • Client solutions (signature application software)
  • e-books
