The s_client command fromOpenSSLis a helpful test client for troubleshooting remote SSL or TLS connections as well as check whether a certificate is valid, trusted, and has a complete certificate chain. The post strives to walk you through various examples of testing SSL connections with different...
Using the OpenSSL s_client, you can check the expiration dates of the website’s certificate from the command line. Here, you will need to combine two commands as reflected below: $openssl s_client-connectkyle.com:4432>/dev/null|openssl x509-noout-dates The-nooutflag suppresses the command...

When using OpenSSL's s_client command to connect to a HTTPS-enabled web server, one receives an error very similar to: Raw 140602938324808:error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure:s23_clnt.c:744: Environment...
You can also use OpenSSL to encrypt or decrypt any file type and to create digests that can be signed and used to validate the contents and the origin of a file. The following are some examples of how you might use theopensslcommand. ...
