python3 -m pip install tuf
By default tuf is installed as pure python package with limited cryptographic abilities. See Install with full cryptographic abilities for more options.
Install with full cryptographic abilities
Default installation supports signature verification only, using a pure Python
ed25519 implementation. While this allows to operate a basic client on
almost any computing device, you will need additional cryptographic abilities
for repository code, i.e. key and signature generation, additional
algorithms, and more performant backends. Opt-in is available via
python3 -m pip securesystemslib[crypto,pynacl] tuf
Install for development
To install tuf in editable mode together with development dependencies, clone the python-tuf repository from GitHub, change into the project root directory, and install with pip (using venv is recommended).
Development installation will Install with full cryptographic abilities. Please check above for possible system dependencies.
python3 -m pip install -r requirements-dev.txt
Verify release signatures
Releases on PyPI are signed with a maintainer key using gpg (see MAINTAINERS.txt for key fingerprints). Signatures can be downloaded from the GitHub release page (look for *.asc files in the Assets section).
