Build with Trufo

Trufo provides content-provenance infrastructure as a service: C2PA Content Credentials, invisible watermarking, trusted certificates, and timestamping, all behind one API. The open-source trufo-py library (v1.0.0) wraps the REST endpoints, manages credentials, and ships runnable quickstarts for every workflow.

Get started in two steps

1. Create an account. Sign up on the Trufo Dashboard, register your organization, and issue API keys for the products you want to use.
2. Install the library and start developing. Install from PyPI (source on GitHub) and sign your first file in under a minute.

pip install trufo

from pathlib import Path

from trufo import sign_c2pa_test
from trufo.util.credentials import TrufoApiKey, load_api_key

api_key = load_api_key(TrufoApiKey.C2PA_SIGN_TEST)

signed_bytes = sign_c2pa_test(api_key, Path("input.jpg").read_bytes())
Path("signed.jpg").write_bytes(signed_bytes)

That is a complete, working example — the signed file carries a C2PA manifest with a certificate and timestamp from Trufo's test environment. The setup guide covers API keys and configuration in detail.
