check SSL certificate from website

You can easily get the SSL certificate from a website from command line. To get the whole thing in text form:

# echo "quit" | openssl s_client -connect $1:443 2>/dev/null | openssl x509 -noout -text
# (long output)

Also, individual attributes can be checked. Get some useful info by using -issuer or -enddate flags

# echo "quit" | openssl s_client -connect godaddy.com:443 2>/dev/null | openssl x509 -noout -issuer | cut -d '/' -f 5 | cut -d "=" -f2
