Quick Start

from tiktok_signer import TikTokSigner

# Generate authentication headers
headers = TikTokSigner.generate_headers(params="aid=1233&app_name=musical_ly")
print(headers)

# Encrypt device registration payload
encrypted = TikTokSigner.encrypt({"device_id": "123456", "os": "android"})

# Decrypt response

Shortcut Functions

The library also provides shortcut functions for convenience:

from tiktok_signer import generate_headers, encrypt, decrypt, encode, decode

# Same as TikTokSigner.generate_headers()
headers = generate_headers(params="aid=1233")

# Same as TikTokSigner.encrypt()
encrypted = encrypt({"key": "value"})

# Same as TikTokSigner.decrypt()
decrypted = decrypt(encrypted_bytes)

# Same as TikTokSigner.encode()
protobuf_data = encode({1: "value", 2: 123})

# Same as TikTokSigner.decode()
dict_data = decode(protobuf_bytes)

Usage Examples

GET Request

import requests
from tiktok_signer import TikTokSigner

# Define parameters
params = {
    "aid": 1233,
    "app_name": "musical_ly",
    "device_platform": "android",

# Convert to query string
query_string = "&".join(f"{k}={v}" for k, v in params.items())

# Generate authentication headers
auth_headers = TikTokSigner.generate_headers(params=query_string)

# Base headers
headers = {
    "User-Agent": "com.zhiliaoapp.musically/2023700040 (Linux; U; Android 9; in_ID; 2203121C; Build/PQ3A.190705.09121607;tt-ok/3.12.13.4-tiktok)",
    "Connection": "Keep-Alive",
    "Accept-Encoding": "gzip",
}
headers.update(auth_headers)

# Send request
url = f"https://api.tiktokv.com/aweme/v1/feed/?{query_string}"
response = requests.get(url, headers=headers)
print(response.json())

POST Request with Body

import requests
from tiktok_signer import TikTokSigner

params = "aid=1233&app_name=musical_ly"

# Request body
data = {
    "username": "example",
    "password": "encrypted_password",
    "mix_mode": 1,
}

# Generate headers with data body
auth_headers = TikTokSigner.generate_headers(
    params=params,
    data=data,
    cookie="sessionid=abc123; tt_csrf_token=xyz789"
)

headers = {
    "User-Agent": "com.zhiliaoapp.musically/2023700040 (Linux; U; Android 9; in_ID; 2203121C)",
    "Content-Type": "application/x-www-form-urlencoded",

print(response.json())

Using Custom Unix Timestamp

import time
from tiktok_signer import TikTokSigner

# Use custom unix timestamp (useful for replay or testing)
custom_unix = int(time.time()) - 60  # 1 minute ago

headers = TikTokSigner.generate_headers(
    params="aid=1233&app_name=musical_ly",
    unix=custom_unix
)

# x-khronos will reflect the custom timestamp
print(f"x-khronos: {headers['x-khronos']}")  # Will show custom_unix value
