It's a simple script running in python that collects SSL/TLS information then it returns the group of information in JSON. It can also connect through your specified SOCKS server.
One of the good things about this script is that it will fully analyze the SSL certificate for security issues and will include the report in the output, CSV, or a JSON file.
You only need to install pyOpenSSL:
pip install pyopenssl
or
pip install -r requirements.txt
./ssl_checker.py -h
usage: ssl_checker.py (-H [HOSTS [HOSTS ...]] | -f HOST_FILE) [-s HOST:PORT]
[-c FILENAME.CSV] [-j] [-J] [-a] [-v] [-h]
Collects useful information about given host's SSL certificates.
optional arguments:
-H [HOSTS [HOSTS ...]], --host [HOSTS [HOSTS ...]]
Hosts as input separated by space
-f HOST_FILE, --host-file HOST_FILE
Hosts as input from file
-s HOST:PORT, --socks HOST:PORT
Enable SOCKS proxy for connection
-c FILENAME.CSV, --csv FILENAME.CSV
Enable CSV file export
-j, --json Enable JSON in the output
-J, --json-save Enable JSON export individually per host
-a, --analyze Enable SSL security analysis on the host
-v, --verbose Enable verbose to see what is going on
-h, --help Show this help message and exit
Port is optional here. The script will use 443 if not specified.
-f, --host-file File containing hostnames for input
-H, --host Enter the hosts separated by space
-s, --socks Enable connection through SOCKS server
-c, --csv Enable CSV file export by specifying filename.csv after this argument
-j, --json Use this if you want to only have the result in JSON
-J, --json-save Use this if you want to save as JSON file per host
-a, --analyze This argument will include security analyze on the certificate. Takes more time. No result means failed to analyze.
-v, --verbose Shows more output. Good for troubleshooting.
-h, --help Shows the help and exit
No problem. Pass -s/--socks argument to the script with HOST:PORT format to connect through SOCKS proxy.

By passing -a/--analyze to the script, it will scan the certificate for security issues and vulnerabilities. It will also mark a grade for the certificate. This will take more time to finish.

Example only with the -j/--json argument which shows the JSON only. Perfect for piping to another tool.

CSV export is also easy. After running the script with -c/--csv argument and specifying filename.csv after it, you'll have something like this:
narbeh@narbeh-xps:~/ssl-checker$ cat domain.csv
narbeh.org
issued_to,narbeh.org
valid_till,2018-07-20
valid_from,2018-04-21

If you want to run this script via docker, simply do create your image and run once:
$ docker build -t ssl-checker .
$ docker run -it --rm ssl-checker -H twitter.com
- Enable timeout for connections and handshakes
- HTML export ability
- Make print_status cleaner and smarter
