Pack Tool
The Intel® Dynamic Application Loader (Intel® DAL) Pack tool is used to:
- Package and sign Java* applet files. The Pack tool accepts a jeff file and a configuration file, and appends the manifest and policy section to the beginning of the file. Afterwards (unless the production flag is set) it signs it with a debug key and produces the final package, which can be uploaded to the Intel® Management Engine (Intel® ME) or Intel® Trusted Execution Engine (Intel® TXE) firmware to run on the virtual machine.
- Package and sign Admin Command Packages (ACPs).
- Extract manifest information from an existing signed package.
- Get the Platform ID (PID) of the current machine - supported beginning with Intel® ME 9.5, including CHV and Intel Atom® SoC (formerly codenamed Bay Trail-I).
- Get the access control value for a specific jeff - supported beginning with Intel ME 11.0.
Beginning with Release 1.16, the Pack tool can work as a stand-alone tool, if the following conditions are met:
- ConfigurationLibrary.jar is included in the PackTool directory.
- jeffp.jar is included in either the PackTool directory or under DALsdk\Plugins\Eclipse.
- bhc.exe (Intel DAL compiler) for each Intel DAL generation is included in either the PackTool directory or under DALsdk\Platform\<PLATFORM>\ PlatformTools\BhcTool.
- dal.jar for each DAL generation is included in either the PackTool directory or under DALsdk\Platform\<PLATFORM>\ PlatformTools.
Command-Line Arguments for Package Option
| Required arguments | Meaning |
|---|---|
| Pack | Specifies that the desired action is to package and sign an applet. |
| -jeff <jeff file> | The jeff file to package (cannot be an empty file). |
| -conf <conf file> | The configuration file to apply to the jeff file. See below for further details on format. |
| Optional arguments | Meaning |
|---|---|
| -sigParams <signature parameters file> | xml file containing the signature parameters to apply to the applet. (See below for further details on format.) |
| -encrypt <encryption key file> | XML file containing the encryption key parameters with which to to encrypt the JEFF byte-code. (See below for further details on format.) |
| -svl <svl file> | A file containing a list of applet security versions. Applets whose security version is equal to or lower than the version specified will not be installed. Removed in API level 7. Use the UpdateSVL command instead for API level 7 and later. |
| -signing | Specifies that the applet is packaged for production. When this argument is inserted, the value of debug.enable in the configuration file must be False. |
| -addpid | Specifies the Platform ID for a production platform. Adds the platform ID value to the manifest file specified in the -conf argument before packaging the pack file. Use for signing a trusted application for a single production platform only (for test purposes). Note: A trusted application signed with this field will load ONLY on the specified platform. This is supported from Intel ME 9.5 and requires the tool to be run with administrative permissions. |
| -temp <temp folder location> | Specifies where to create the Temp folder for the packing flow. |
| -help | Displays help for the the command line arguments. |
| -out <out file> | Specifies a file to which the output result will be copied. If not specified, the output file will be located in the Out directory from which the tool was invoked. |
Configuration File Format
The configuration file format contains properties with the format property:value. There can be empty lines (new line is "\n" or "\r\n") and/or white spaces (spaces and tabs) between:
- line start
- property
- value
- end of line (Those whitespaces will be trimmed).
The supported properties can be found in the Trusted Application Manifest.
