DESCRIPTION

swugenerator is a tool running on host to create and modify SWUpdate's Update files (SWU). SWU file contains a meta description of the release (sw-description), and swugenerator adds components to a template passed from command line. This tool requires openssl to run and to sign the SWU. It is goal of the tool to fill the gap with Yocto/OE, where SWU generation is done by classes in the meta-swupdate layer, but other buildsystems like Debian or Buildroot have no tools to create a SWU.

The tool signs the SWU and can encrypt the artifacts. The tool parses the libconf based sw-description (tool does not work for JSON based sw-description) and provides the following features:

  • replace occurrencies of variables found in the CONFIG file
  • add sha256 to each artifact
  • check if an artifact should be encrypted and encrypts it
  • sign sw-description with one of the methods accepted by SWUpdate
  • pack all artifacts into a SWU file
