Are TLS fingerprints consistent across different versions of chrome? #364

There are many values for the impersonate parameter

BrowserTypeLiteral = Literal[
    # Edge
    "edge99",
    "edge101",
    # Chrome
    "chrome99",
    "chrome100",
    "chrome101",
    "chrome104",
    "chrome107",
    "chrome110",
    "chrome116",
    "chrome119",
    "chrome120",
    "chrome123",
    "chrome124",
    "chrome99_android",
    # Safari
    "safari15_3",
    "safari15_5",
    "safari17_0",
    "safari17_2_ios",
    # alias
    "chrome",
    "edge",
    "safari",
    "safari_ios",
    "chrome_android",
]

What I want to know is, do these values correspond to the same TLS fingerprint? For example, whether there is a difference between the tls fingerprint of chrome99 and chrome100. If there's a difference, I need to pick it up randomly to confuse the target site

Yes, some of them are indeed the same. To figure out it, you can try to visit the following targets with each type and compare the results.

Thank you for your testing ideas. I have conducted some tests.

The code and results used in the tests are as follows, which can also provide some references for others:

from curl_cffi import requests

# Define the impersonate parameters you want to test
browser_types = [
    "chrome99",
    "chrome100",
    "chrome101",
    "chrome104",
    "chrome107",
    "chrome110",
    "chrome116",
    "chrome119",
    "chrome120",
    "chrome123",
    "chrome124",
    # "chrome99_android",
]

# URLs to check TLS fingerprints
urls = [
    "https://tls.browserleaks.com/json",
    # "https://tools.scrapfly.io/api/fp/ja3"
]

def fetch_tls_fingerprint(browser_type):
    headers = {"User-Agent": "curl_cffi"}
    for url in urls:
        response = requests.get(url, impersonate=browser_type, headers=headers)
        print(f"Browser Type: {browser_type}\nURL: {url}\nTLS Fingerprint:\n{response.text}\n{'-'*60}\n")

# Loop through each browser type and fetch the TLS fingerprint
for browser in browser_types:
    fetch_tls_fingerprint(browser)
