# Python-TLS-Client-Async

[![PyPI version](https://img.shields.io/pypi/v/async_tls_client.svg)](https://pypi.org/project/async_tls_client/)
[![Python versions](https://img.shields.io/pypi/pyversions/async_tls_client.svg)](https://pypi.org/project/async_tls_client/)
[![License](https://img.shields.io/badge/license-MIT-blue.svg)](https://opensource.org/licenses/MIT)

Asyncio-first TLS client for Python with advanced fingerprinting capabilities. Modern fork
of [Python-TLS-Client](https://github.com/FlorianREGAZ/Python-Tls-Client) with enhanced features and active maintenance.

```python
from async_tls_client import AsyncClient
import asyncio


async def main():
    async with AsyncClient(
            client_identifier="chrome120",
            random_tls_extension_order=True
    ) as client:
        response = await client.get("https://tls.peet.ws/api/all")
        print(f"Detected TLS fingerprint: {response.json()['tls']['ja3_hash']}")


asyncio.run(main())
```

## Features ✨

- **Full Async Support**: Built with asyncio for high-performance concurrent requests
- **Modern TLS Fingerprinting**: JA3, JA4, HTTP/2 fingerprints and TLS 1.3 support
- **Client Profiles**: 50+ preconfigured clients (Chrome, Firefox, Safari, iOS, Android)
- **Advanced Configuration**:
    - Custom TLS cipher suites & extensions
    - HTTP/2 and QUIC protocol support
    - Certificate pinning and compression
    - Proxy support (HTTP/S, SOCKS4/5)
- **Auto-Cookie Management**: Session persistence with configurable cookie jars
- **Request Manipulation**: Header ordering, pseudo-header customization, and priority control

## Why This Fork? 🚀

The fork was created due to the lack of updates in the original repository, while the underlying GoLang
library [tls-client](https://github.com/bogdanfinn/tls-client) continues to evolve actively. This project aims to keep
up with the latest developments in the GoLang library and provide a modern, asynchronous interface for Python users.

### Recommendations:

- Monitor changelogs for deprecation warnings in future minor releases
- Avoid direct reliance on internal modules like `async_tls_client.structures` or `async_tls_client.cookies`
- Consider contributing feedback on the proposed changes through GitHub issues

## Installation 📦

```bash
pip install async_tls_client
```

## Quickstart 🚀

### Basic Usage

```python
from async_tls_client import AsyncClient
import asyncio


async def main():
    async with AsyncClient("chrome120") as client:
        response = await client.get(
            "https://httpbin.org/json",
            headers={"X-API-Key": "secret"},
            proxy="http://user:pass@proxy:port"
        )
        print(f"Status: {response.status_code}")
        print(f"Headers: {response.headers}")
        print(f"JSON: {response.json()}")


asyncio.run(main())
```

## Advanced Features 🔧

### Custom Fingerprint Configuration

```python
client = AsyncClient(
    ja3_string="771,4865-4866-4867-49195-49199-49196-49200-52393-52392-49171-49172-156-157-47-53,0-23-65281-10-11-35-16-5-13-18-51-45-43-27-17513,29-23-24,0",
    h2_settings_order=["HEADER_TABLE_SIZE", "MAX_CONCURRENT_STREAMS"],
    pseudo_header_order=[":method", ":authority", ":scheme", ":path"],
    header_order=["accept", "user-agent", "accept-encoding"],
    force_http1=False,
    cert_compression_algo="brotli"
)
```

### Certificate Pinning

```python
client = AsyncClient(
    certificate_pinning={
        "api.bank.com": [
            "sha256/7HIpactkIAq2Y49orFOOQKurWxmmSFZhBCoQYcRhJ3Y=",
            "sha256/YLh1dUR9y6Kja30RrAn7JKnbQG/uEtLMkBgFF2Fuihg="
        ]
    }
)
```

### Proxy Support

```python
response = await client.get(
    "https://api.example.com",
    proxy="socks5://user:pass@proxy:1080"
)
```

## Asynchronous Design 🚧

The client leverages Python's asyncio through three key strategies:

1. **Non-blocking I/O**
    - Network operations run in separate threads using `asyncio.to_thread`
    - Go TLS client handles remain managed in background executors

2. **Session Management**
    - `AsyncClient` context manager handles automatic cleanup
    - Connection pooling with automatic keep-alives
    - Cookie persistence across requests

3. **Resource Optimization**
    - Zero-copy body handling for large responses
    - Lazy initialization of heavy resources
    - Automatic memory cleanup of Go pointers

## Packaging 📦

### Windows

```bash
--add-binary 'async_tls_client/dependencies/tls-client-64.dll;async_tls_client/dependencies'
```

### Linux

```bash
--add-binary 'async_tls_client/dependencies/tls-client-x86.so:async_tls_client/dependencies'
```
