Secure -Software Install SIS Tools Overview

Secure -Software Install SIS Tools Overview -

The Secure Software Install SIS Tools enable you to create, sign, -decompile and preinstall SIS files.

Description

The Secure Software Install SIS Tools -component comprises the following PC-side command-line tools:

The MakeSIS tool -creates unsigned SIS files based on the information provided in an input package -(PKG) file.
The SignSIS tool -signs SIS files using a certificate and private key.
The CreateSIS tool -is a wrapper around the MakeSIS, SignSIS, and MakeKeys tools, which automates -the process of generating and signing SIS files. It supports creating new -SIS files from package (PKG) files, signing existing package files and generating -private-public key pair and certificate requests for signing.
The DumpSIS tool -decompiles input SIS file and extracts the corresponding PKG and source files.
The InterpretSIS tool -enables device creators to preinstall SIS files on a device system drive or -memory card image. The InterpretSIS tool can be invoked either through the -BUILDROM tool when creating a data drive image, or as a stand-alone tool.

Required background

Before you start, you must -be familiar with the following:

Public -Key Cryptography
Digital -Certificates

Key concepts and terms

PKG File: A package (PKG) file contains information required by the SIS file -creation tools to create a SIS file.
SIS File: A Symbian Installation Source (SIS) file is a collection of executables -and data files, packaged in a way that the software installer can install -them onto a device. SIS files can be preinstalled on a device.
Signing: A SIS file must be signed with a digital signature, which is used in -verifying the identity of the vendor of an installation file. This ensures -that the file has not been tampered with since it was signed. For details -see, Signing.
Eclipsing: Eclipsing is a mechanism to upgrade files existing on the ROM drive, -by installing a new version of the same on the RAM drive. For details see, Eclipsing.
System Upgrade Packages: System upgrade packages allow device manufacturers to overcome the -restriction of having a stub SIS file in the ROM drive for eclipsing. For -details see, System -Upgrade Packages.
Auto-propagation: Auto-propagation is a process of automatically installating software -packages from the media card when it is inserted into the Symbian device. -For details, see Package -Propagation.

Typical Uses

The SIS tools can be used to perform -the following:

Create and sign -an installation file

Symbian application developers can create -installation packages using MakeSIS and sign them using SignSIS. -Alternatively, the CreateSIS tool, which is a wrapper around MakeSIS and SignSIS, -can be used to create and sign an installation file. For details see Creating and Signing an Installation -File
Upgrade OS components

The -software installer enables a device manufacturer to replace binaries and data -files in ROM, for example, to fix a software issue, by means of eclipsing. -For details, see Upgrading -an OS Component.
Preinstall -applications

Device creators can preinstall applications on device -system drive or memory card image. For details, see Preinstalling -Applications.
