- Comprehensive Testing: Full test suite with unit and integration tests
Legacy Version
A legacy version (0.2.x) of this project is available for users who need the previous implementation. For more information, see LEGACY_VERSION.md or visit the legacy branch on GitHub.
Installation
Install from PyPI:
pip install otdf-python
Quick Start
Basic Configuration
from otdf_python.sdk_builder import SDKBuilder
# Create and configure SDK using builder pattern
builder = SDKBuilder()
builder.set_platform_endpoint("https://platform.example.com")
builder.client_secret("your-client-id", "your-client-secret")
# Build the SDK instance
sdk = builder.build()
Advanced Configuration
from otdf_python.sdk_builder import SDKBuilder
# Create SDK with additional configuration options
builder = SDKBuilder()
builder.set_platform_endpoint("https://platform.example.com")
builder.set_issuer_endpoint("https://auth.example.com")
builder.client_secret("your-client-id", "your-client-secret")
# Examples, for local development
# Use HTTP instead of HTTPS
builder.use_insecure_plaintext_connection(True)
# Or
# Skip TLS verification
builder.use_insecure_skip_verify(True)
# Build the SDK instance
sdk = builder.build()
Encrypt Data
from io import BytesIO
# Create TDF configuration with attributes
config = sdk.new_tdf_config(attributes=["https://example.net/attr/attr1/value/value1"])
# Encrypt data to TDF format
input_data = b"Hello, World!"
output_stream = BytesIO()
manifest, size, _ = sdk.create_tdf(BytesIO(input_data), config, output_stream)
encrypted_data = output_stream.getvalue()
# Save encrypted data to file
with open("encrypted.tdf", "wb") as f:
f.write(encrypted_data)
Decrypt Data
# Read encrypted TDF file
with open("encrypted.tdf", "rb") as f:
encrypted_data = f.read()
# Decrypt TDF
tdf_reader = sdk.load_tdf(encrypted_data)
decrypted_data = tdf_reader.payload
# Save decrypted data
with open("decrypted.txt", "wb") as f:
f.write(decrypted_data)
