# SSL Checker
#### Python script that collects SSL information from hosts
## About
It's a simple script running in python that collects SSL information then it returns the group of information in JSON. It can also connects trough your specified SOCKS server.
One of the good thing about this script, is that it will full analyze the SSL certificate for security issue's and will include the report in the output or CSV file.
## Requirements
You only need to installl pyOpenSSL:
`pip install pyopenssl`
## Usage
```
./ssl_checker.py -h
usage: ssl_checker.py [-H [HOSTS [HOSTS ...]] | -f HOST_FILE] [-s HOST:PORT]
[-c FILENAME.CSV] [-j] [-a] [-p] [-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
-a, --analyze Enable SSL security analysis on the host
-p, --pretty Print pretty and more human readable Json
-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
`-a, --analyze` This argument will include security analyze on the certificate. It will take more time.
`-p, --pretty ` Use this with `-j` to print indented and human readable JSON
`-h, --help` Shows the help and exit
## Censored?
No problem. Pass `-s/--socks` argument to the script with `HOST:PORT` format to connect through SOCKS proxy.

## Security Analyze
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.**

narbeh@narbeh-xps:~/ssl-checker$ ./ssl_checker.py -j -p -H narbeh.org:443 -a

## JSON And CSV Output
Example only with the `-j/--json` and `-p/--pretty` arguments which shows the JSON only. Perfect for piping to another tool.
```
narbeh@narbeh-xps:~/ssl-checker$ ./ssl_checker.py -j -p -H narbeh.org:443 test.com
{'narbeh.org': {'cert_alg': u'sha256WithRSAEncryption',
'cert_exp': False,
'cert_sn': 338163108483756707389368573553026254634358L,
'cert_ver': 2,
'issued_o': None,
'issued_to': u'narbeh.org',
'issuer_c': u'US',
'issuer_cn': u"Let's Encrypt Authority X3",
'issuer_o': u"Let's Encrypt",
'issuer_ou': None,
'valid_from': '2018-04-21',
'valid_till': '2018-07-20',
'validity_days': 90},
'test.com': {'cert_alg': u'sha256WithRSAEncryption',
'cert_exp': False,
'cert_sn': 73932709062103623902948514363737041075L,
'cert_ver': 2,

'issuer_ou': None,
'valid_from': '2017-01-15',
'valid_till': '2020-01-24',
'validity_days': 1104}}
```
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
issuer_ou,None
cert_ver,2
cert_alg,sha256WithRSAEncryption
cert_exp,False
issuer_c,US
issuer_cn,Let's Encrypt Authority X3
issuer_o,Let's Encrypt
validity_days,90
cert_sn,338163108483756707389368573553026254634358
```
## Todo
- Enable timeout for connections and handshakes
- HTML export ability
