Python script To extract SSL certificate issue and expiry date from a specific domain entered by the user in Python 3.11.5, you can use the ssl and socket libraries.
Python Program Code:
import ssl
import socket
def SSL_info(domain):
try:
context = ssl.create_default_context()
with socket.create_connection((domain, 443)) as sock:
with context.wrap_socket(sock, server_hostname=domain) as ssock:
cert = ssock.getpeercert()
issue_date = cert[‘notBefore’]
expiry_date = cert[‘notAfter’]
return issue_date, expiry_date
except (socket.error, ssl.SSLError, ConnectionError) as e:
return None, None
if name == “__main__”:
domain = input(“Enter the domain (e.g., example.com): “)
issue_date, expiry_date = SSL_info(domain)
if issue_date and expiry_date:
print(f”SSL Certificate Information for {domain}:”)
print(f”Issue Date: {issue_date}”)
print(f”Expiry Date: {expiry_date}”)
else:
print(f”Unable to retrieve SSL certificate information for {domain}. Please check the domain name or make sure it uses SSL (HTTPS).”)
