What is SSL? How to use and what does SSl mean?

SSL is a security protocol. The services provided are: authenticating users and servers to ensure that data is sent to the correct clients and servers; Encrypt data to prevent data from being stolen in the middle of the process; Maintain the integrity of the data and ensure that the data is not altered during transmission.

An SSL certificate is a type of digital certificate that is similar to an electronic copy of a driver's license, passport, and business license. Because it is configured on the server, it is also known as an SSL server certificate. It is issued by a globally trusted certificate authority after verifying the identity of the server.

The SSL certificate is installed on the server to achieve the dual functions of authentication and data encryption transmission.

To apply for an SSL certificate, you need to go through the steps of certificate purchase, application submission, certificate issuance, installation and deployment, which are generally relatively simple.

1.Certificates are available.

The commonly used SSL certificates are divided into DV certificates, OV certificates and EV certificates according to the verification method.

2.Submit an application.

Once you have purchased the certificate that suits you, you can start to submit information for issuance. This link is relatively simple, and the main thing is that the enterprise submits relevant information on the certificate platform.

3.Certificate issuance.

After completing the previous steps of submitting an application, the issuing authority verifies the applicant's information.

4.Install and deploy.

Installation and deployment refers to the installation and deployment of the certificate on the server, and only in this way can the HTTPS protocol be enabled. For installation and deployment, different servers operate in different ways, so you are advised to consult the service provider that purchased the certificate.

Internet information security technology has always been a matter that people attach great importance to and continue to work on. As people become more and more dependent on Internet technology, the personal information we leave on the Internet is stolen and sold by criminals at will, and we urgently need more secure access. In order to provide more secure and reliable access, various security protocols have emerged.

1. What does SSL mean?

SSL, English spelling is Secure Sockets Layer, that is, Secure Sockets Layer, SSL is a security protocol that provides security and data integrity for our network communication, it can encrypt the network connection at the transport layer, so that our access is more secure and reliable.

2. What is the role of SSL?

The SSL security protocol has only two major functions:

First, SSL prevents hackers from eavesdropping on data. Nowadays, many people use shopping** or online banking to conduct ** transactions, if you do not apply SSL security protocol to encrypt data, your bank card, credit card,**, address and other information may be abused, and even sold to some fraudulent organizations for fraudulent activities.

Second, SSL can prevent data from being tampered with by hackers during transmission and ensure the integrity of data transmission. For example, when you shop online or log on to online banking, if your data is tampered with by hackers, it is very likely to cause significant monetary losses, so it is necessary to use SSL.

3. How to apply for an SSL certificate.

First of all, we should choose a formal and authoritative CA agency, there are many digital certificate authorities, but some digital certificate authorities in order to compete for the market, indiscriminately issue certificates, and the certification has been canceled, therefore, you need to pay attention when choosing. Generally speaking, the more well-known digital certificate authorities mainly include: Symantec, Comodo, Geotrust, etc., and many SSL certificate service providers such as Alibaba Cloud have cooperated with these CA agencies.

Secondly, there are three types of SSL certificates that can be applied: EV, OV, and DV, and users need to choose the appropriate SSL certificate according to their respective circumstances.

1. EV type. It is mainly suitable for industries with high security standards, such as banking, insurance, P2P, investment, wealth management, crowdfunding, etc.

2. OV type. It is mainly suitable for education and training, e-commerce, Internet news, etc.

3. The DV type is mainly suitable for some small customers, individuals and test use, such as blogs.

Thirdly, submit the attestation materials to the CA to verify your company's qualifications.

Finally, carry out organization verification, domain name verification, and ** verification.

After completing the above steps, it will take about 3-7 business days for the CA agency to send the certificate to your email.

The above is the knowledge answer I have compiled for you about what SSL means and what is the role of SSL.

The full name of SSL is Secure Sockets Layer, which refers to the Secure Sockets Protocol; SSL and its successor, Transport Layer Security, is a security collaboration that provides security and data integrity for network communications. TLS and SSL encrypt network connections between the transport layer and the application layer. Shoho.

SSL has two main functions: encrypted data transmission and server authentication.
