CFD is a tool that allows you to check one or more domains to see if they are protected by CloudFlare or not. The check is carried out based on five criteria: 3 headers in the HTTP response, IP, and SSL certificate issuer. The check result can be displayed on the screen or saved to a file.
Requirments
To use Cfd you need to install Cargo and Rust. Just paste into your terminal window:
curl https://sh.rustup.rs -sSf | sh
cargo install cfd
Usage
cfd [OPTIONS] <TARGET>
Arguments
<TARGET> A domain, domains divided by newline char or a file with domains.
Flags
-h, --help Prints help information
-V, --version Prints version information
Options
-d Outputs a detailed result for each domain based on five checks.
-f Outputs only domains without Cloudflare presence.
-o <OUTPUT> The path to the folder where the cfd_report.{txt or csv} file will be stored. If a file won't be specified, output will be printed to stdout. If the detailed flag is set, the output will include checking details.
-h, --help Print help
-V, --version Print version
Usage examples
Every example will be shown with this set of domains: cloudflare.com, example0.com, example1.com, example2.com
1. Not detailed and not filtered output. If you provide a folder for outputting the result through the -o
option, the result will be written in the form of cfd_report.csv
cfd resources/cfd_work.txt
Output:
2. Detailed and not filtered output to stduout. If you provide a folder for outputting the result through the -o
option, the result will be written in the form of cfd_report.csv
cfd resources/cfd_work.txt -d
Output:
3. Detailed and filtered output to stduout. If you provide a folder for outputting the result through the -o
option, the result will be written in the form of cfd_report.csv
cfd resources/cfd_work.txt -d -f
Output:
4. Detailed and filtered output to stduout. If you provide a folder for outputting the result through the -o
option, the result will be written in the form of cfd_report.txt
cfd resources/cfd_work.txt -f
Output:
cloudflare.com
example1.com
In-Code examples
Complex checking:
use cfd::run;
#[tokio::main]
async fn main(){
let target = "example.com\ncloudflare.com";
let checker = run(target.to_string()).await.unwrap();
assert_eq!(checker.cf_detected_domains().await.len() == 1, true);
}
Check if an IP belongs to the Cloudflare IP range:
use cfd::cf_ips::CFIPs;
#[tokio::main]
async fn main(){
let cf_ips = CFIPs::load().await.unwrap();
assert!(cf_ips.check_ip_v4("131.0.72.1"));
}
