How to get certificate using OpenSSL

Get the SSL certificate of a website using openssl command:

A one-liner to extract the certificate from a remote server in PEM format, this time using sed

echo | openssl s_client -servername **NAME** -connect **HOST:PORT** |\
  sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > certificate.crt

openssl s_client -connect www.google.com:443 2>/dev/null </dev/null |  sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p'

With SNI

openssl s_client -showcerts -servername www.example.com -connect www.example.com:443 </dev/null
