# Python-TLS-Client-Async
[](https://pypi.org/project/async_tls_client/)
[](https://pypi.org/project/async_tls_client/)
[](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 Configuration
```python
from async_tls_client import AsyncClient
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={
"HEADER_TABLE_SIZE": 65536,
"MAX_CONCURRENT_STREAMS": 1000,
"INITIAL_WINDOW_SIZE": 6291456,
"MAX_HEADER_LIST_SIZE": 262144
},
supported_signature_algorithms=[
"ECDSAWithP256AndSHA256",
"PSSWithSHA256",
"PKCS1WithSHA256",
"ECDSAWithP384AndSHA384",
"PSSWithSHA384",
"PKCS1WithSHA512",
],
certificate_pinning={
"example.com": [
"sha256/AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA="
]
}
)
```
## Client Profiles 🕶️
Preconfigured client identifiers (https://github.com/bogdanfinn/tls-client/blob/master/profiles/profiles.go):
| Browser/Framework | Available Profiles |
|-------------------|---------------------------------------------------------------------------------------------|
| Chrome | chrome_103 - chrome_133 (including PSK variants: 116_PSK, 116_PSK_PQ, 131_PSK, 133_PSK) |
| Firefox | firefox_102 - firefox_135 |
| Safari (Desktop) | safari_15_6_1, safari_16_0, safari_ipad_15_6 |
| Safari (iOS) | safari_ios_15_5 - safari_ios_18_0 |
| Opera | opera_89 - opera_91 |
| Android (OkHttp) | okhttp4_android_7 - okhttp4_android_13 |
| iOS (Custom) | mms_ios (v1, v2, v3), mesh_ios (v1, v2), confirmed_ios, zalando_ios_mobile, nike_ios_mobile |
| Android (Custom) | mesh_android (v1, v2), confirmed_android, zalando_android_mobile, nike_android_mobile |
| Cloudflare | cloudscraper |
## 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 📦
When using PyInstaller/PyArmor, include the shared library:
### 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'
```
### macOS
```bash
--add-binary 'async_tls_client/dependencies/tls-client-arm64.dylib:async_tls_client/dependencies'
```
