Currently, encrypt communication is experiencing a big boom. After cases of data leakage and monitoring of personal communications, even ordinary users are beginning to worry about their data and are looking for options in security. In this context, there is a growing interest in SSL certificates, which will enable secure transmission of communication between the user and the server. In today’s article, we will show you how to correctly install an SSL certificate on a virtual server.
What is SSL?
SSL (Secure Sockets Layer) is a non-commercial open protocol and currently one of the most us methods for securing data transmissions within the Internet between a server with a web presentation and a browser (user).
The principle of the function of SSL certificates is bas on asymmetric encryption, where each of the communicating parties has two encryption keys – public and private. The public key can made public, and if data is encrypt. With this public key, it is ensur that only the owner of the us public key will.Able to decrypt the data with his private key (use for encryption).
On the other hand, if data is encrypt
with the private key, only the public key can decrypt it. That wouldn’t make much sense, since everyone has a public key. However, if the public key carries the information that it belongs to a specific entity (company) and this confirmation is given by a trust authority, we are sure that we are communicating with the right entity and not with an impostor (use for determining authenticity).
The SSL protocol uses digital certificates to ensure encryption of transmitt data and authentication of the server . The fact that we are connect to a website secur using the SSL protocol can be recogniz by the address of the page, which also contains the letter “s”, e.g.
