unblob relies on various tools for extracting the contents of a blob. These
extractors are either third party tools (e.g. 7z), or part of unblob (available
directory or specific ones next to the handler, e.g.:
To use unblob with all supported formats, all extractors need to be installed.
See the Installation section on how to install extractors for various methods. You don't need to install any of these if you use Docker or Nix, as all extractors are included in those solutions.
Checking installed extractors¶
There is a
--show-external-dependencies CLI option, which displays the name of
the extractors used by unblob and shows if they are available for unblob to use
$ unblob --show-external-dependencies The following executables found installed, which are needed by unblob: 7z ✓ debugfs ✓ jefferson ✓ lz4 ✓ lziprecover ✓ lzop ✓ sasquatch ✓ sasquatch-v4be ✓ simg2img ✓ ubireader_extract_files ✓ ubireader_extract_images ✓ unar ✓ zstd ✓
NOTE: This option does NOT check the version of the extractors.
❌: If you installed unblob from source, you need to install these manually.
✅: These extractors come with unblob, check pyproject.toml and poetry.lock for current versions.

Maintained projects and forks¶
We maintain a fork of several extractors, with many fixes and improvements. They are also available on GitHub:
- Jefferson for extracting JFFS2 is also a project of ONEKEY
- Fork of sasquatch based on squashfs-tools
- Fork of ubi_reader Python scripts for extracting UBI and UBIFS images
