Caterpillar - The simple and parasitic web proxy with spam filter

How to works

Basic structure

You <-> Proxy client (Python) <-> Parasitized proxy server (Optional, PHP) <-> On the Web

For example, build a simple web debugging proxy on the shared servers.

Spam filtering strategy

• K-Anonymity test - Estimating whether the characters has been arranged by humans. (use Have I Been Pwned)
• Image spam containing characters that look very similar to CAPTCHA. (use TrueCaptcha)

(Optional) Before to use

If you have an will be parasitize server that you want to proxy, you can install the index.php file.

How to use

1. Write a file .env(Linux) or settings.ini(Windows). Like this:

[settings]
PORT=5555
SERVER_URL=http://example.org
CA_KEY=ca.key
CA_CERT=ca.crt
CERT_KEY=cert.key
CERT_DIR=certs/
OPENSSL_BINPATH=openssl
CLIENT_ENCODING=utf-8
LOCAL_DOMAIN=example.org
PROXY_PASS=http://127.0.0.1:3000
MASTODON_SERVER=
MASTODON_USER_TOKEN=
TRUECAPTCHA_USERID=
TRUECAPTCHA_APIKEY=

1.1. (Optional) Install RootCA

sudo apt-get install -y ca-certificates
sudo cp ca.crt /usr/local/share/ca-certificates/caterpillar-ca.crt
sudo update-ca-certificates

2. Run python3 server.py and set HTTP(S) proxy in your web browser (e.g. Firefox)

3. Test 100MB/SSL, 1GB/SSL, 10GB/SSL download and check the speed (e.g. https://speed.hetzner.de/1GB.bin)

4. Enjoy it

5. (Optional) With Cloudflare, we can expect to accelerate the 4x speed and reduce the network stuck.

(Optional) For Mastodon users

1. In [php-httpproxy installed directory]/settings.ini or .env, set SERVER_URL variable to localhost in .env (e.g. SERVER_URL=localhost)
2. In [mastodon installed directory]/env.production, set http_proxy variable to http://localhost:5555 (e.g. http_proxy=http://localhost:5555)
