What does ssl mean? many people know it but don't know why. It is simply known that SSL is a security certificate, but it is not very clear about what ssl is and the role of SSL, so let's talk about it in detail.

SSL is an international standard name, which can be understood as a safe transport protocol. And SSL protocol is between application layers, which provides security guarantee for data transmission, and SSL protocol can be divided into two layers: SSL recording protocol (SSL Record Protocol): it is based on reliable transmission protocols (such as TCP). It provides support for high-level protocols such as data encapsulation, compression, encryption and other basic functions. The other is the handshake protocol, which is on the record, which is mainly used for identity authentication, negotiation of encryption algorithm, exchange of encryption keys and so on before transmitting data. This is the correct answer to what ssl is.

Once you have an understanding of what ssl means, let's take a look at what SSL does. It has two main functions: encrypting the data in the transmission process, authenticating the user identity (high-intensity authentication based on digital certificates), and authenticating the user and the server to ensure that the data is sent to the correct client and server. It is also used to ensure the security of data transmission on Internet, using data encryption (Encryption) technology to ensure that data will not be intercepted and eavesdropped during transmission on the network. At present, it is mainly used for sending secure e-mail, visiting secure sites, online tendering and bidding, online signing, online ordering, secure transmission of online documents, online office, online payment, online tax payment, online shopping and other secure online electronic transaction activities.

This is the answer to what ssl means, and you can see that SSL is very secure and worth configuring.
