In principle any OpenSSL or even LibreSSL can be used as a helper. Reading RFC 3280 it seems this is the condition for self-issued, a distinct concept from self-signed: "A certificate is self-issued if the DNs that appear in the subject and issuer fields are identical and are not empty.In general, the issuer and subject of the certificates that make up a path are different for each certificate. openssl is installed by default on most Unix systems. We can check SSL/TLS connection with s_client command. To check SSL certificate expiration date on a Live website, first define and export the variables as shown. As of OpenSSL 0.9.8 you can choose from smtp, pop3, imap, and ftp as starttls options. 1. The option takes an additional argument n which has a unit of seconds. s_lient is a tool used to connect, check, list HTTPS, TLS/SSL related information. Before we start with checking our connections, we need to make sure our OpenSSL is up to date, so let us check which version are we running with the following command.
