Securesystemslib is a cryptography interface for signing and verifying digital signatures. It is developed for the TUF and in-toto projects: the key and signature containers are compatible with metadata formats from those projects.
Under the hood, Securesystemslib can use various digital signing systems (e.g. cryptography, PIV hardware keys and multiple cloud-based key management systems).
The default installation supports pure-Python ed25519 signature
verification only. To enable other schemes and
signature creation, securesystemslib can be installed with extras. See
pyproject.toml for available optional dependencies.
# Install with ed25519, RSA, ECDSA sign and verify support
pip install securesystemslib[crypto]# ...or with HSM (e.g. Yubikey) support
pip install securesystemslib[hsm]python-securesystemslib.readthedocs.io
