# OpenTDF Python SDK

Unofficial OpenTDF SDK for Python


## Features

- **TDF Encryption/Decryption**: Create and decrypt TDF files with policy-based access control
- **Flexible Configuration**: Support for various authentication methods and platform endpoints
- **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](docs/LEGACY_VERSION.md) or visit the [legacy branch on GitHub](https://github.com/b-long/opentdf-python-sdk/tree/0.2.x).


## Installation

Install from PyPI:
```bash
pip install otdf-python
```

## Quick Start

### Basic Configuration

```python
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

```python
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

```python
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

```python
# 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)

```
