How do I get SSL TLS certificate?

I want to make a payment with a merchant account and I think this is important. I was able to receive payment without an SSL certificate, but I have no idea how to get one. Could anyone help me?
I want to know whether I need any certificate of some certificate authority (CA) or not. Well, it depends what kind of payment you want to receive. SSL doesn't mean you are secure. For example if you want to use Amazon payments there are only ways for sending data - http protocol is blocked.

What you need are certificates from some CA (like Verisign) because their certificate is publicly trusted.

What is SSL TLS certificate?

It's all about SSL/TLS Certificates.

They are signed keys that identify and authenticate the owner of a website. They are issued to organizations by Certificate Authorities (CA). This article is one of the first ones that describes SSL/TLS certificates in details. And we hope it will be helpful to you.

A Brief Introduction. The Internet is an interconnection of many smaller networks: local area networks, private intranets, and public web servers. A user connects to a website using a web browser. The browser needs to locate the website in a logical network topology and then establish a session with the server. But since the browser has no information on which server is used, it has to do some research on the web to find the address of the website.

The browser must now contact the website. The connection will be encrypted using SSL/TLS, otherwise known as Transport Layer Security. These are not standard Internet protocols but rather extensions to the standard TCP/IP protocols that provide privacy, authentication, and data integrity. The most popular protocols using SSL/TLS are the Secure Sockets Layer (SSL) and the TLS protocols. HTTPS (HTTPS: Hypertext Transfer Protocol over Secure Sockets Layer) was introduced to standardize use of SSL/TLS.

What Is SSL? To start, let us introduce the SSL Protocol. Secure Sockets Layer (SSL) protocol is a mechanism that provides confidentiality, integrity, and authentication of data transmitted over a communication channel such as the Internet. It consists of a series of related messages and operations that can be used between a client and a server to negotiate a security association over an insecure communication link. There are several versions of the protocol, each designed for a specific application.

We will explain the basics of the protocol. SSL is more complex than the SSH protocol, which is also in widespread use. However, the basic concept of the protocol has been used to build protocols such as SSH2 and IPSec. We can thus learn enough about SSL from studying those protocols. The SSL protocol itself has also influenced such protocols as IPsec, TLS, and SMTPS.

There are four parts in SSL Protocol: Client Hello A request sent from a client to a server for a secure connection. Client Hello is encrypted with client-chosen secret key.

How does an SSL/TLS certificate work?

Certificates that work by encrypting data are called SSL certificates.

In the case of a secure sockets layer (SSL) certificate, the information on the certificate is secured with the help of some algorithms, whereas in the case of transport layer security (TLS) certificates the information is secured by encrypting it.

What are SSL/TLS certificates used for? SSL/TLS certificates are used in secure websites to ensure safe transmission of data. All the information in the website is encrypted so that people cannot see it and make up personal information.

What are the different kinds of SSL/TLS certificates? There are basically two types of certificates, which are used for SSL/TLS: Single-domain certificates are used to secure a particular domain name, ie a website, whereas multi-domain certificates are used to secure more than one domain. Let us now understand these two types of certificates in detail: SSL/TLS certificate is given to a single domain or website, ie the certificate is used for securing only one website. For example, if you own, your SSL/TLS certificate issued to that particular website, which is called the host name of your SSL/TLS certificate. The certificate will be used for securing all the webpages of the website.

If you have two domains like and, then the respective SSL/TLS certificates are issued for these two websites. The certificates will secure the information that is present in the domains mentioned in the DNS records of the respective nameservers. The domains of which the SSL/TLS certificates are issued are called the subject names of the SSL/TLS certificates. The subject names are used by the browser and the server when communicating over a secure connection to decide which certificate should be sent to the client. The browser also requires the subject name to use for generating the session keys and for authenticating the server.

Single-domain SSL/TLS certificates are often purchased by businesses with a single domain to secure their online business. Multi-domain certificate. If you own multiple websites, then you may need an SSL/TLS certificate that can be used to secure both the websites.

What is the difference between SSL certificate and TLS certificate?

It's a long but quite simple answer: TLS is a protocol that the client and the server need to agree on.

For most purposes they should both use TLS, but some servers don't run the very best TLS implementation out there, so they use SSL instead.

SSL is an implementation of TLS and it also defines some mechanisms for other protocols, eg HTTP. It isn't actually a protocol in itself; it's something one can use to encrypt, sign and authenticate data via (most often) the TLS protocol.

What Is An SSL/TLS Certificate?

SSL or Transport Layer Security is a method for secure communication between a client and a server.

The SSL protocol was designed for secure Internet transactions. This technology is used on the Web, by e-mail servers, and by remote access connections.

SSL/TLS (SSL: Secure Sockets Layer, TLS: Transport Layer Security) is one of the newer technologies for data encryption. The security of encrypted data is achieved by means of cryptographic procedures.

You can purchase SSL certificates from many web hosting services that are designed to add SSL support to your websites. We recommend that you choose a service provider that offers not only the traditional HTTP support, but also the more powerful SSL functionality.

SSL/TLS is a newer technology than HTTP. SSL functions like an "on/off switch" on the Web. When SSL is switched on, it works as a secure communications channel between your browser and a web server. It's a very important part of your online security because all the private information you submit on the Web will be protected. SSL can also be used to secure the data transmitted via FTP, HTTP and other communications protocols.

How Does SSL Work? SSL uses a public key to encrypt the data exchanged between the client and the server. The "key" is exchanged in the form of a digital certificate, which includes an algorithm, a timestamp, the server's public key, the name of the server, a unique ID number, and other basic information. Once the certificate is received, the client and the server exchange the public keys and use them to create a secret key that is shared only between the two parties.

This encrypted secret key is what's known as the symmetric encryption key. With symmetric encryption, you and I both have the same secret key that will open the lock on my house. This key is called a session key, and it is used to encrypt the data that is sent between the client and the server.

When the browser is ready to request a file from a server, the browser generates the session key. The browser passes the session key to the server, which then generates its own session key and sends the public key of the server back to the browser. When the browser and the server exchange these public keys, they can use the symmetric key to decrypt the data.
