A library that provides cryptographic and general-purpose routines for Secure Systems Lab projects at NYU
Project description
securesystemslib
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).
Installation
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]

Testing
tox is used for testing. It can be installed via
pip and executed from the
command line in the root of the repository.

Legacy key migration
Use migrate_keys script to convert key pairs generated
with legacy keys or interface modules to a consistent standard format, which
is compatible with CryptoSigner.
