SignSIS - Installation file signer syntax in Software Installation Toolkit

SignSIS is a tool that digitally signs software installation (SIS) files using a certificate and private key. The public key certificate and private key are specified as command line arguments to SignSIS (see Command-line syntax below).

The following diagram shows how SignSIS is used to sign an install package (SIS file).

From an MSDOS command-line prompt (or batch file) the syntax for using SignSIS is as follows:

SignSIS [-?] [-c...] [-i] [-r] [-s] [-u] [-v] sis_input [sis_output [certificate key [passphrase] ] ]

where

Argument	Description
`-?`	Output this help information
`-cd`	Sign using a DSA algorithm
`-cr`	Sign using an RSA algorithm
`-i`	Output licence information
`-o`	Report on content of SIS file (after any other operation)
`-s`	Sign SIS file (requires SIS file, certificate, key and passphrase)
`-u`	Remove most recent signature from SIS file
`-v`	Verbose output
`sis_input`	The SIS file to be signed, unsigned or investigated
`sis_output`	The SIS file generated by signing or unsigning
`certificate`	The certificate file used for signing
`key`	The certificate's private key file
`passphrase`	The certificate's private key file's passphrase

Before digitally signing a SIS file, SignSIS may prompt for a password to access the private key file if required.
