SecurSign® is a command-line driven server-based application that can apply and verify digital signatures in PDF documents. SecurSign can also apply standard Adobe® Acrobat® security features to PDF documents. SecurSign is designed to run in tandem with other processes in an unattended environment and to handle high-volume and on-demand production needs.

Memory Requirements

Minimum free memory available to run the application: 512 MBytes

Windows Installation

Windows installation is handled by the installer and does not require any special handling.

Unix Installation

Setting environmental variables (All Unix Platforms)

In this release, there are two additional environmental variables that need to be set for SecurSign on all UNIX platforms. If you run SecurSign from the secursign script created during installation, these environmental variables will be set by the script. If you run secursignapp directly, you will need to set these environmental variables to run SecurSign. Once SecurSign is installed, you can view the variables needed by looking at the secursign script created by the installer. 

Setting the Appligent home directory (All Unix Platforms)

The environmental variable that stores the location of the Appligent home directory is APPLIGENT_HOME. The default location for the Appligent home directory is /usr/local/appligent. The Appligent home directory contains the library files and resources needed to run SecurSign. It also contains license information for SecurSign.


export APPLIGENT_HOME=/usr/local/appligent 

Setting the APDFL library path ( All Unix except AIX )

The APDFL library path must be added to the LD_LIBRARY_PATH variable. The APDFL library path is located in a subdirectory of the APPLIGENT_HOME directory.
The path should be set to ${APPLIGENT_HOME}/APDFLX.X.X/Libs



Setting the APDFL library path ( AIX Only )

The APDFL library path for AIX must be added to the LIBPATH variable. The APDFL library path is located in a subdirectory of the APPLIGENT_HOME directory.
The path should be set to ${APPLIGENT_HOME}/APDFLX.X.X/Libs.



Registration Numbers for SecurSign 5.0

In previous versions of SecurSign, the SecurSign registration number was required as a command line option with the -r flag each time secursignapp was run. A secursign script was provided that automatically added -r and the registration number to the secursignapp command line when the script was run.

In the current release, in addition to getting the registration number from the command line, SecurSign can get the registration number from a license file in the Appligent home directory. On UNIX systems, license files are created by the installation script and stored in the ${APPLIGENT_HOME}/license directory.  For Windows, the license file is created by the installer and stored in the /All Users/Application Data/Appligent/License directory. With a valid license file, the -r is no longer required on the command line. The -r option can still be used as in previous versions, and will override the value in the license file.
