FILE AUTHENTICATION
VeriShield File Signing Tool
96 VX 520 REFERENCE GUIDE
-F, -f Name of the application file to
sign (*.out, *.lib, or other file
type).
Required for development
terminals and for deployment
terminals.
-S, -s Name of the signature file
(*.p7s) for the VeriShield File
Signing Tool to generate for the
target application file.
Required for development
terminals and for deployment
terminals.
-L, -l Specifies to store the target
application file to sign and
authenticate in the flash (drive F:)
file system.
If you do not use this switch to
specify flash as the target file
destination, it is stored by default
in the RAM file system (drive I:).
Optional entry.
This switch assigns an F: prefix
to the name of the *.out or
*.lib file to download, and also
stores this information in the
signature file as part of the special
filetype attribute.
Note: Signature files must be
downloaded into the
target file group’s RAM.
If the target file is authenticated,
the corresponding *.p7s file is
moved to the same memory area
as the target file it authenticates.
For example, if the target file is
stored in flash (F:), its *.p7s file
is moved into the flash file
system. If, however, you set the
*FA variable in the file group’s
CONFIG.SYS file to 0, all
signature files are deleted from
RAM when file authentication is
complete. Removing *.p7s files
will prevent application files from
executing after a back-to-back
download.
