How does the secure HTTPS website protocol work?

Post by subornaakter40 »

Yes, HTTP is very popular and convenient, but if the site uses an unprotected HTTP protocol, all the information you requested from the Internet may, passing through one of the many intermediate points of the Internet, be intercepted and fall into the hands of intruders. As an example - access to the Internet through a common Wi-Fi in any public place. The protocol that guarantees the security of using a site is HTTPS, which has encryption support.

Applications of HTTPS

HTTPS is in demand everywhere where the marketing list of senior homes protection of transmitted information is of great importance. These are systems related to the transfer of payments, processing of personal data of clients (for example, any forms of feedback). A number of well-known services on Yandex, namely Yandex.Money, Metrika, Passport, Direct, Mail, Taxi function precisely via HTTPS.

In order for your browser to work via HTTPS, there is no need to perform any special configuration steps: it is supported everywhere and, when necessary, it starts automatically.

Why does HTTPS guarantee security?

Encryption of transmitted information occurs via an additional cryptographic protocol SSL/TLS. It is this that transforms data into a form inaccessible to perception, it is like a wrapper for HTTP. Thanks to SSL/TLS, any two unfamiliar Internet users can establish a secure connection for data exchange on an unprotected channel.

A simple example: you need to pay your provider for using the Internet. You go to the site, then to your user account, perform the payment procedure, entering the password, the amount to pay, the bank card number at different stages. It is clear that you are interested in non-disclosure of this data, but initially the provider's site uses an unprotected HTTP protocol, it is through this protocol that communication with you is carried out.

Is it possible to set up a secure path for yourself via HTTPS in a channel that is open to viewing (for almost every visitor)? Yes, it is possible, and the scheme is surprisingly simple.

How does data transfer occur in a secure connection?

Again, a simple example: you need to send an item to someone. You can send it by mail or courier, and to prevent theft, you put the item in a box and put a lock on it. The recipient receives the package, but without the key, he cannot open it. He adds another lock and sends the package back to you. You remove your lock (but the second one, which is not yours, remains, so the contents are safe) and send the box back to the recipient. Now he can remove his lock and take the contents.

This is the principle by which encrypted messages are exchanged. In essence, the recipient has received the key to the cipher from you, which both you and he now have. Any encrypted messages sent are now unreadable by outsiders, because they do not have the key. You could simply send the recipient a box with an attachment, and the key in a separate parcel, but there is a high risk that the key will fall into the hands of intruders and they will open your parcel.
