Jimmy Hedman on Twitter: "@markusgranseth och SNI så kan du

With SNI support, outbound web service requests specify the hostname to connect to as part of the TLS handshake. This information allows the server to present the correct certificate to the client. Domain fronting is a technique of replacing the desired host name in SNI with another one hosted by the same server or, more frequently, network of servers known as Content Delivery Network. When a client uses domain fronting, it replaces the server domain in SNI (unencrypted), but leaves it in the HTTP host header (which is encrypted by TLS) so that server can serve the right content.

A modern web server can serve multiple domains from a single IP address because it uses a virtual host to match each domain name to the domain's files on your server. SNI can be useful with modern web browsers and browsers that do not support SNI will have default certificate and shows a warning. At present, IPv6 addresses have replaced IPv4 to serve websites. Browsers will deal with the exact domain name to which the visitor wants to connect with during secured SSL handshake. 2020-07-04 · When the web server requires SNI (Server Name Indication), the standard s_client syntax returns no certs: $ openssl s_client -connect :443 CONNECTED (00000005) write:errno=54 --- no peer certificate available --- No client certificate CA names sent --- SSL handshake has read 0 bytes and written 0 bytes --- New, (NONE), Cipher is (NONE) SNI helps you save money as you don’t have to buy multiple IP addresses.

Server Name Indication (SNI) is an extension to the Transport Layer Security (TLS) protocol that enables servers to use multiple SSL certificates on one IP address. In practical terms, this means: As the number of available IPv4 addresses becomes smaller and smaller, the remaining addresses can be allocated more efficiently.

The biggest and perhaps the only concern with SNI was its scalability. Initially, there weren’t many web browsers and servers supporting SNI technology. Today, that scenario has turned upside down. Security plays a big role on the internet. As a result, there are standards, certificates, and protocols that try to protect users as well as servers from malicious attacks. One of these protocols is called Transport Layer Security (TLS). Since this system is problematic, however, server name indication (SNI) serves as an extension.
