TLS and SSL in online payments

No matter how you take payments online – whether you have card or Direct Debit payments you will want to make sure y'all're using SSL (technically it'due south now TLS or "Transport Layer Security" but the terms are used interchangeably). If y'all're taking card payments – it's not a choice – SSL is required for PCI compliance.

While it's not required for Direct Debit payments, SSL and the associated lock icon, light-green bar and https address that comes with an SSL secured site have go synonymous with online payment security.

What is SSL?

TLS and its predecessor SSL ("Secure Sockets Layer") are standard security technology that establish a secure link between a website and a visitor's web browser (or a mail service server and customer). All communications transmitted through this link are encrypted. Therefore, sensitive information similar credit card numbers are first encrypted, and so sent to the website owners, who can decrypt the information once they receive it. This ways anyone who tries to intercept the information on the way won't become anything but encrypted (unreadable) data.

What exercise you need to employ SSL?

All browsers have the capability to use SSL protocol to interact with secured web servers, still, both the browser and the server require an SSL certificate to establish a secure connection.

What is an SSL certificate?

An SSL certificate is a digital document that authenticates a website'south identity and and so encrypts information sent from the website to the server using SSL security applied science. It says to users that you are who you say you are and the issuer has verified that to be true.

When y'all have an SSL Document, your payment site will display:

A padlock symbol in your client'south web browser when your site is opened
The https prefix in front end of your URL address in the browser

An SSL certificate consists of a "key pair" (a public and private primal which work together to plant the encrypted connection) and the following data:

The certificate holder's name
The certificate'south serial number and expiration date
A copy of the certificate holder's public key
The digital signature of the certificate-issuing authority

What should you recollect nigh when getting an SSL document?

There are 2 important questions to ask when getting an SSL document:

What does the SSL certificate verify? - SSL certificates can either verify your domain only (the SSL Document Issuer only validates that you own the domain) or your domain and your identity. Domain-validated certificates offer your customers no balls of your identity. Y'all should therefore but use a domain validated certificate on an internal server or if users already trust your organization and know they are on the correct website.
Who is the SSL Document from? - Anyone tin create an SSL certificate - you can self sign a certificate (for free), notwithstanding, browsers but trust certificates that come up from a trusted SSL Certificate Issuer (as well known as a "Certificate Authority" or "CA" - a visitor which has been audited against security and authentication standards). Self signed or free SSL certificates generally lead to error messages from browsers.

How does SSL work?

There are v simple steps to the SSL process:

A browser tries to connect to a secured website.
The server shares a copy of its SSL Certificate and its public key.
The browser checks and authenticates the SSL Certificate. If the browser trusts the SSL Certificate it then sends back a session key to the server using the server'south public key.
The server confirms that it recognises and trusts the issuer of the SSL certificate. This is known as the "SSL handshake" and information technology begins a secure session that protects message privacy and message integrity.
The browser and the server share encrypted information over the secure channel.
