This is a release candidate: please download and test it OpenSSL 1.1.1t is now available, including bug and security fixesīeta 1 of OpenSSL 3.1 is now available. OpenSSL 3.0.8 is now available, including bug and security fixes Security Advisory: one high and seven moderate severity fixes If not specified then an attempt is made to connect to the local host on port 4433. Options -connect host:port This specifies the host and optional port to connect to. No need to compile anything or jump through any hoops, just click a few times and it is installed, leaving you to doing real work.
It is easy to set up and easy to use through the simple, effective installer. It is a very useful diagnostic tool for SSL servers. The Win32/Win64 OpenSSL Installation Project is dedicated to providing a simple installation of OpenSSL for Microsoft Windows. If the handshake fails then there are several possible causes, if it is nothing obvious like no client. The sclient command implements a generic SSL/TLS client which connects to a remote host using SSL/TLS.
If the connection succeeds then an HTTP command can be given such as GET / to retrieve a web page. would typically be used (https uses port 443).

The project’s technical decision making is managed by the OpenSSL Technical Committee (OTC) and the project governance is managed by the OpenSSL Management Committee (OMC). If you have configured your web server for this domain, the web server finds it and serves the specific conf for it, in this case with the right certificate.The OpenSSL Project develops and maintains the OpenSSL software - a robust, commercial-grade, full-featured toolkit for general-purpose cryptography and secure communication. You are telling the web server that the server name you are looking for is. Openssl s_client -connect :443 -servername When adding the servername option to openssl: Your web server doesn't know what is the server name it should looking for a certificate and serves the default one that in your case is. Since SNI was implemented you can server multiple certificates per ip address, so when using this command: Several years ago, web servers (and browsers) didn't support Server Name Indication so you could only have one certificate per ip address. Openssl s_client -connect :443 (not the command you told but my first tried command)
