Certify is a python tool designed to check the security of SSL/TLS certificates.

Certify

Certify is a powerful and easy-to-use Python tool designed to check the security of SSL/TLS certificates. It provides a range of options for analyzing certificates and identifying potential security risks, including the ability to display subject alternative names, subject common names, organization name, TLS version, cipher, certificate fingerprint hashes, JARM hash, certificate serial number, certificate pinning status, certificate authority verification, and certificate validity.

Certify also includes a number of features for identifying common certificate misconfigurations, such as expired, self-signed, mismatched, revoked, and untrusted certificates. The tool supports scanning individual hosts or lists of hosts, and allows for flexible output options, including the ability to write output to a file or display it in JSON format.

Whether you're a security researcher, network administrator, or just someone who wants to ensure the security of your online communications, Certify is an indispensable tool for analyzing SSL/TLS certificates and identifying potential security risks. With its powerful features and intuitive interface, it makes it easy to stay on top of the latest security threats and keep your systems safe and secure.

Installation Through PIP

To install dependencies, use the following command:

pip install -r requirements.txt

To import certify as module, install it using the following command:

pip install certifycert

Installation with Docker

This tool can also be used with Docker. To set up the Docker environment, follow these steps (trying using with sudo, if you get any error):

docker build -t certify:latest .

Using the Certify as command-line tool

To run the Certify on a hostname, provide the hostname with the -d flag:

python3 certify -d example.com

For an overview of all commands use the following command:

python3 certify -h

The output shown below are the latest supported commands.

usage: python3 certify [-h] [-v] [-d hostname] [-l file_path] [-p port] [-an] [-cn] [-on] [-tv] [-cipher] [-hash hash_name] [-jarm] [-sn] [-pin] [-av] [-vu] [-ex] [-ss] [-mm] [-re] [-un]
                       [-o file_path] [-j] [-silent]
