oscalkit

In development

Barebones Go SDK and CLI tool for parsing OSCAL, translating between OSCAL-formatted XML and JSON and for converting from OpenControl projects in to OSCAL.

Installing

You can download the appropriate oscalkit command-line utility for your system from the GitHub Releases page and run it from your local machine directly. For easier execution, you can include it in your $PATH environment variable. If you prefer, you can download and install via the included RPM/Deb packages on Linux or Homebrew recipe on macOS. A Docker image is also made available on Docker Hub.

Homebrew

$ brew tap opencontrol/homebrew-oscalkit
$ brew install oscalkit

Docker

Running the oscalkit Docker container requires either bind-mounting the directory containing your source files or passing file contents in to the command via stdin.

$ docker pull opencontrolorg/oscalkit:<version>
$ docker run -it --rm -v $PWD:/data -w /data opencontrolorg/oscalkit convert oscal-core.xml

or via stdin:

$ docker run -it --rm opencontrolorg/oscalkit convert < oscal-core.xml

Usage

NAME:
   oscalkit - OSCAL toolkit

USAGE:
   oscalkit [global options] command [command options] [arguments...]

VERSION:
   0.0.0

COMMANDS:
     convert   convert between one or more OSCAL file formats
     validate  validate files against OSCAL XML and JSON schemas
     help, h   Shows a list of commands or help for one command

GLOBAL OPTIONS:
   --debug, -d    enable debug command output
   --help, -h     show help
   --version, -v  print the version

Convert between XML and JSON

oscalkit can be used to convert one or more source files between OSCAL-formatted XML and JSON.

   oscalkit convert oscal - convert between one or more OSCAL file formats

USAGE:
   oscalkit convert oscal [command options] [source-files...]

DESCRIPTION:
   Convert between OSCAL-formatted XML and JSON files. The command accepts
   one or more source file paths and can also be used with source file contents
   piped/redirected from STDIN.

OPTIONS:
   --output-path value, -o value  Output path for converted file(s). Defaults to current working directory
   --output-file value, -f value  file name for converted output from STDIN. Defaults to "stdin.<json|xml|yaml>"
   --include-yaml                 If source file format is XML or JSON, also generate equivalent YAML output

Examples

Convert OSCAL-formatted NIST 800-53 declarations from XML to JSON:

$ oscalkit convert oscal SP800-53-declarations.xml

Convert OSCAL-formatted NIST 800-53 declarations from XML to JSON via STDIN (note the use of "-"):

$ cat SP800-53-declarations.xml | oscalkit convert oscal -

Convert from OpenControl project to OSCAL [Experimental]

Depends on usnistgov/OSCAL #92

oscalkit also supports converting OpenControl projects to OSCAL-formatted JSON. You will need both the path to the opencontrol.yaml file and the opencontrols/ directory which is created when you run a compliance-masonry get command.

NAME:
   oscalkit convert opencontrol - convert from OpenControl format to OSCAL "implementation" format

USAGE:
   oscalkit convert opencontrol [command options] [opencontrol.yaml-filepath] [opencontrols-dir-path]

DESCRIPTION:
   Convert OpenControl-formatted "component" and "opencontrol" YAML into
   OSCAL-formatted "implementation" layer JSON

OPTIONS:
   --yaml, -y  Generate YAML in addition to JSON
   --xml, -x   Generate XML in addition to JSON

Examples

Convert OpenControl project to OSCAL-formatted JSON:

$ oscalkit convert opencontrol ./opencontrol.yaml ./opencontrols/

Validate against XML and JSON schemas

The tool supports validation of OSCAL-formatted XML and JSON files against the corresponding OSCAL XML schemas (.xsd) and JSON schemas. XML schema validation requires the xmllint tool on the local machine (included with macOS and Linux. Windows installation instructions here)

NAME:
   oscalkit validate - validate files against OSCAL XML and JSON schemas

USAGE:
   oscalkit validate [command options] [files...]

DESCRIPTION:
   Validate OSCAL-formatted XML files against a specific XML schema (.xsd)
   or OSCAL-formatted JSON files against a specific JSON schema

OPTIONS:
   --schema value, -s value  schema file to validate against

Examples

Validate FedRAMP framework in OSCAL-formatted JSON against the corresponding JSON schema

$ oscalkit validate -s oscal-core.json fedramp-annotated-wrt-SP800-53catalog.json

Developing

oscalkit is developed with Go (1.9+). If you have Docker installed, the included Makefile can be used to run unit tests and compile the application for Linux, macOS and Windows. Otherwise, the native Go toolchain can be used.

Dependency management

The dep dependency management tool is used to vendor the application's dependencies. The vendor/ folder containing the dependencies is checked in with the source. With dep, you can verify the dependencies as follows:

$ dep ensure

Compile

You can use the included Makefile to generate binaries for your OS as follows (requires Docker):

Compile for Linux:

$ GOOS=linux GOARCH=amd64 make

Compile for macOS:

$ GOOS=darwin GOARCH=amd64 make

Compile for Windows:

$ GOOS=windows GOARCH=amd64 make

Releasing

The GoReleaser tool is used to publish oscalkit to GitHub Releases. The following release artifacts are currently supported:

• OSX binary
• Linux binary
• Windows binary
• Docker Image
• RPM package
• Deb package
• Homebrew recipe
