How to Download the SSL Certificate from a Weburl on Linux




Many times we come across SSL websites that had certificates. We might need to deploy certificates in our wallets, Keystore, etc.

We can directly download those certificates from the URL on Linux server.

Let's says we want to download amazon.in cert use below command

$ true | openssl s_client -connect amazon.in:443 2>/dev/null | openssl x509



[himanshu@oel7server tmp]$ true | openssl s_client -connect amazon.in:443 2>/dev/null | openssl x509
