scai-generator Python CLI

CLI Environment Setup

To run the SCAI CLI tools and examples, the following packages are required on a minimal Ubuntu system. We assume Ubuntu 20.04 or higher.

sudo apt install git python3 python3-dev python3-venv virtualenv build-essential

Then, set up the Python virtualenv for the SCAI CLI tools from this repo's root directory.

make VENVDIR=<dest dir> py-venv

Basic CLI Invocation

source $VENVDIR/bin/activate

Generate a ResourceDescriptor

To generate ResourceDescriptors for SCAI AttributeAssertion or Report fields:

scai-gen-resource-desc -o <output filename> [-n <resource name> -d -u <resource URI>] [-r <resource filename>] [-l <resource download location>] [-c] [-t <resource media type>]

:warn: Note: Because at least one of name, uri or digest fields are required in ResourceDescriptors, the tool will throw an error if none of these options are passed in.

Generate an AttributeAssertion

To generate AttributeAssertions for a SCAI Report:

scai-attr-assertion -a <attribute string> -o <output filename> [-t <target filename>] [-e <evidence filename>] [-c <conditions filename>]

:warn: Note: Since the conditions field in AttributeAssertions can be an arbitrary JSON object, the tool assumes that this object has been written to a file beforehand.

Generate a SCAI report

To generate a SCAI Report:

scai-report -s <subject artifact filenames> -a <attribute assertion filenames> -o <output filename> [-p <producer filename>]

Note: The generated SCAI report document is a valid in-toto Statement.

For a full list of CLI tool options, invoke with the -h option.
