Web servers usually use a well-known TCP port 80. If the port is not specified in a URL, browsers will use this port when sending HTTP request. For example, you will get the same result when requesting and .
The system can also be used for client authentication in order to limit access to a web server to authorized users. To do this, the site administrator typically creates a certificate for each user, which the user loads into their browser.
Public Key: It is public in nature and is accessible to all the users who communicate with the server. The private key is used for the decryption of the data that has been encrypted by the public key.
Why do so many people use the WWW frequently? In terms of popularity, WWW usage has been around since the creation of the internet, and its use primarily as a subdomain emerged by accident.
Как ни говори он вешает на ящик свой замок в свой черед отправляет обратно вам. Вы получаете ящик под двумя замками, снимаете свой — теперь это безопасно — также отправляете еще раз. Адресат получает, наконец, ящик, в любой момент котором висит только его замок, открывает его равным образом достаёт то, что вы ему послали.

SSL (Secure Sockets Layer) and TLS (Transport Layer Security) encryption can be configured in two modes: simple and mutual. In simple mode, authentication is only performed by the server. The mutual version requires the user to install a personal client certificate in the web browser for user authentication.
When a trusted authority signs a digital certificate, it guarantees that the data encrypted using the certificate has been protected by a mechanism that belongs to the server.
There will be issues with caching some information over HTTPS. Public caching of those that previously took place won't happen again.
Part of SSL's significance lies in the fact that it was the first widely used and broadly implemented network protocol to enable cryptographically secured communications between client and server systems. SSL uses public key and private https://gradeproject.eu/ key encryption and other cryptographic functions to secure connections between devices communicating over a TCP/IP network.
Любое действие в интернете — это обмен данными. Каждый раз, когда вы запускаете видеоролик, посылаете сообщение в социальной сети или открываете любимый сайт, ваш компьютер отправляет концентрирование к нужному серверу также получает по вине него выражение.
SSL is a negotiation process between a web client and a web server that involves the transmission of SSL certificates.
Симметричный ключ — у обеих сторон ес один ключ, с через которого они передают извещение.
Since HTTPS uses encryption and HTTPS does not, it inevitably requires more processing overhead that impacts response times and latency. However, with improving hardware and optimization techniques, this performance gap between HTTP vs HTTPS continues to shrink.
