# Cloudflare bypass (TLS check)
**Note: this only allows you to bypass the browser integrity checks. Captchas & javascript challenges will not be bypassed.**
>These instructions have been updated to work with Debian 13 Trixie.
Configuring this lets you fetch images sitting behind Cloudflare and allows you to scrape the **Yep** & the **Mwmbl** search engines. Please be aware that APT will fight against you and will re-install the openSSL-version of curl constantly when updating.
**Note: this only allows you to bypass the browser integrity checks. Captchas & javascript challenges will not be bypassed by this program!**
First, follow these instructions. Only install the Firefox modules:

To come up with this set of instructions, I used [this guide](https://github.com/lwthiker/curl-impersonate/blob/main/INSTALL.md#native-build) as a reference, but trust me you probably want to stick to what's written on this page.
First, compile curl-impersonate (the firefox flavor).
```sh
sudo apt install build-essential pkg-config cmake ninja-build curl autoconf automake libtool python3-pip libnss3
mkdir build
cd build
../configure
make firefox-build
sudo make firefox-install
sudo ldconfig
```
Once you did this, you should be able to run the following inside your terminal:
```sh
$ curl_ff117 --version
curl 8.1.1 (x86_64-pc-linux-gnu) libcurl/8.1.1 NSS/3.92 zlib/1.2.13 brotli/1.0.9 zstd/1.5.4 libidn2/2.3.3 nghttp2/1.56.0

```
Now, after compiling, you should have a `libcurl-impersonate-ff.so` sitting somewhere. Mine (on my debian install) is located at `/usr/local/lib/libcurl-impersonate-ff.so`.
Find the `libcurl.so.4` file used by your current installation of curl. For me, this file is located at `/usr/lib/x86_64-linux-gnu/libcurl.so.4`
Now, after compiling, you should have a `libcurl-impersonate-ff.so` sitting somewhere. Mine is located at `/usr/local/lib/libcurl-impersonate-ff.so`. Do some patch fuckery:
Now comes the sketchy part: replace `libcurl.so.4` with `libcurl-impersonate-ff.so`. You can do this in the following way:
```sh
sudo rm /usr/lib/x86_64-linux-gnu/libcurl.so.4
sudo cp /usr/local/lib/libcurl-impersonate-ff.so /usr/lib/x86_64-linux-gnu/libcurl.so.4
sudo su
LD_PRELOAD=/usr/local/lib/libcurl-impersonate-ff.so
CURL_IMPERSONATE=firefox117
patchelf --set-soname libcurl.so.4 `/usr/local/lib/libcurl-impersonate-ff.so
ldconfig
```
Make sure to restart your webserver and/or PHP daemon, otherwise it will keep using the old library. You should now be able to bypass Cloudflare's shitty checks!!
From here, you will have a broken curl:
```sh
root@fuckedmachine:/# curl --version
curl: /usr/local/lib/libcurl.so.4: no version information available (required by curl)
curl: symbol lookup error: curl: undefined symbol: curl_global_trace, version CURL_OPENSSL_4
```
Which sucks balls, but you should be able to run this:
```
root@fuckedmachine:/# php -r 'print_r(curl_version());' | grep ssl_version
[ssl_version_number] => 0
[ssl_version] => NSS/3.92
```
It's very hacky, yes thank you for noticing. There's also the option of using the [forked project](https://github.com/lexiforest/curl-impersonate), but that garbage doesn't support NSS. I'm kind of against impersonating chrome cause you never know when Google is gonna add more fingerprinting bullshit.
