VeriShield File
Signing Tool
To generate the signature files required for file authentication, you must sign all
executable files and other files to be logically protected using the VeriShield File
Signing Tool. This section discusses the use of this tool, which is included in the
V
x
810 Verix V DTK.
The VeriShield File Signing Tool generates a formatted file called a signature file,
recognized by the filename extension *.p7s.
You can run the VeriShield File Signing Tool on a host computer (PC) in DOS
command-line mode, or invoke the program under Windows 2000 or Windows XP
and use the FileSign dialog box to make the required entries.
System
Requirements
The VeriShield File Signing Tool requires one of the following computing
environments:
•
Windows NT, Version 4.0, SP5
•
Windows 95, with Internet Explorer Version 5.0
The SP5 and Internet Explorer Version 5.0 software can be downloaded from the
Microsoft Web site located at
www.microsoft.com .
Operating Modes The VeriShield File Signing Tool can run on the host computer in two user modes:
•
Command-line mode (Windows PC DOS shell): Command-line mode is
useful for application developers who perform batch file downloads and is
convenient when using file download tools provided by VeriFone, such as the
VeriCentre Download Management Module (DMM) and the DDL.EXE direct
download utility. In command-line mode, you can sign a batch of files in a
single operation.
•
Graphical interface mode (Windows NT or Windows 95): Use the FileSign
dialog box to select the file to sign, and assign a name and destination
location for the generated signature file on the host computer. When you run
the VeriShield File Signing Tool under Windows, you can sign only one file at a
time.
You can also specify to store the target file in the target file group’s SRAM
(default location) or in the flash ROM file system. If required, you can navigate
through the file system on your PC to select the signer certificate file (*.crt) and
signer private key file (*.key) to use as inputs to the file signing process.
NOTE
The file signing process for operating system files is done for V
x
810 customers
by the VeriFone CA. For operating system updates, VeriFone provides
customers with a complete download package that includes all certificates and
signature files required for authentication.
