Everything you need to know about SSL
What is SSL?
SSL (Secure Sockets Layer) is a type of encryption that is commonly used for communication purposes on the internet. Transport Layer Security, a successor to the now-obsolete Secure Sockets Layer, is an advanced cryptographic protocol developed to offer secure communications over an intranet network.
SSL works by encrypting data sent over a web connection before sending it to the recipient. The encrypted information is delivered through the network in a clear, transportable format.
This allows users to view and check the content of the transmission without the need to decode the details of the transmission, making SSL an ideal form of encryption for confidential documents.
However, despite the many benefits of SSL and the robustness of its cryptographic protocol, some issues still persist and need to be resolved. SSL uses the Diffie-Caliper Group (D CG), a family of cryptographic protocols designed to break down the security protection provided by one-way SSL.
Among these is the use of Elliptic Curve cryptography, an advanced form of elliptic curve cryptography. An elliptic curve is a mathematical structure that shows the value of a prime number.
Elliptical curves were first introduced as an encryption or protection technique for digital signatures in 1998 but have gained greater significance as a solution to many security issues over the years.
SSL and D CG share many properties and are vulnerable to attacks such as phishing. SSL uses Diffie-Calculator, a type of calculator that performs some of the functions of elliptical curve equations.
This makes it more susceptible to attack since an external source can calculate the curve parameters used by servers. In addition, a server in the wrong configuration, such as a firewall that blocks SSL/TLS traffic, can reveal the private key used as a bearer for a session.
With the use of automated scanning tools for SSL/TLS, clients can check whether they are protected or not from attacks by using CA certificates and making use of trusted CA certificates that pass on the authentication message to the browser.
How an SSL certificate works
With more people becoming comfortable and familiar with the internet, it’s no surprise that they are asking how SSL works
People want to go online to their favorite social networking sites, or shop on their favorite shopping sites and have their information remain secure. In order for this to happen, they must use secure connections – such as those provided by SSL.
SSL (Secure Socket Layer) is a type of standard that is used on the Internet to transmit information back and forth between two or more networks.
SSL works by generating a ‘public key’ and a ‘private key’. The public key is just what it sounds like – a number that every website will use to identify itself on the internet. The private key, however, is only used by the actual website and nobody else.
When you enter in any information on the web page you are visiting, the information goes into the public key server and is available to anyone who has access to that server. You don’t need to be a computer genius to understand how this works; it’s just really very simple actually.q
SSL works by encrypting the details of the website you are visiting along with the key you have chosen. This will then create a ‘Cipher’.
A cipher is a number that is random and unique. This number is then combined with the public key you have chosen and creates an ‘encryption handshake’. This encryption handshake creates a secure connection between you and the site you are trying to reach.
In order for you to understand how SSL works, it helps to look at an example. One of the most common questions about how SSL works comes from the acronym SSL, SMTP, and IMAP.
These are the most common protocol types that are used when thinking about how SSL works. All of these acronyms stand for ‘Secure Socket Layer’. It should be noted that while SMTP and IMAP are completely different, they still use the same encryption methods.
What you might not realize is that when you are looking at how SSL works, you are also looking at how websites handle secure sockets layer (SSL).
SSL, as stated above, is a protocol that handles encrypted data transfers between two different web servers. When you receive an email from a friend on a social networking site, it is possible that the link that was embedded in the email was tampered with or altered in some way.
If this happened, the email would not have been able to be sent to the intended recipient – it would have been intercepted as being unsolicited.
The SSL protocols make sure that emails can be sent safely over the internet. Without these protocols, this email could have been intercepted and could have contained malware such as viruses or spyware that could have caused the email to be misused.
However, it is easy to see how SSL certificates help protect us from the perils that can befall our private communications. Anybody with an internet connection can read the information that is encoded into digital certificates. This means that nearly everyone can view your personal data.
Types of SSL certificates
There are actually a couple of different types of SSL Certificates which you are able to take advantage of depending on your company’s various needs.
These different SSL types offer distinct advantages to your company, and their verification processes vary quite a bit.
You will find that there are some major differences between the different SSL types as well.
One of the major differences between the different types of ssl certificates is what kind of validation that is performed on them. In most cases, there are two different options with this type of certificate, and they include wildcard and self-signed validation.
The wildcard type of validation requires that the server have at least one or more top-level domain names listed in its SSL certificate database.
Any other domain names that are listed here are not allowed to be handled within the wildcard certificate.
On the other hand, when it comes to self-signed SSL certificates, there is no need to validate the websites that are requesting the certificate.
In addition to the two major options with these types of certificates, there are also three validation levels that are available.
The higher the number of validation levels that are present in the certificate type, the higher the level of security that is offered for the websites.
Typically, websites will only be able to receive these types of SSL Certificates with the highest three-validation levels.
These include the highest level of trust which is called wildcard encryption.
Next is the certificate type which offers the highest level of verification which is called self-signed validation.
Finally, there are the certificate types that are only offered for websites that have been verified by the CA.
These three types of SSL certificates offer different levels of authentication when it comes to handling the websites which are requesting such certificates.
Wildcard encryption involves the use of wildcards to transmit the subject domain’s name as the first portion of an SSL Certificate. This method is commonly used for secure websites which accept and respond to challenge-response messages sent from the servers.
When the request message is then decrypted using the Diffie-Wald algorithm, the result is then sent back to the client. However, when the server’s response message is not properly handled, this leads to the subject domain’s name getting the name wild card encryption, which prevents it from being sent again.

The next option for online certificates is the Extended Validation Certificate which offers a higher level of authentication which is different from wildcard encryption.
On the other hand, certificate providers who choose to process this type of certificate will also have to put in extra effort when it comes to verifying whether a domain name is registered in the right name.
Since different types of SSL certificates available in the market may have different reasons for being granted access to the Internet, it is important for webmasters to choose the one that best serves their purpose.
In addition, there are also different types of SSL Certificates according to the websites they are used for.
These include Top-Level Domain (TLD) certificates, which are provided by different global network organizations such as ICANN and Assigned Numbers Authority (ANN) and standard certificates which are normally issued by web host companies or other qualified security authorities.
However, these certificates do not need any higher validation level compared to the other types of SSL certificates because these top-level domains already have the required level of authentication.
In most cases, businesses prefer to get certificates from different providers so that it would be easier for them to customize and manage their websites.
When it comes to choosing the right provider for the task, it is important to remember that some may be more experienced and capable of handling various tasks than others. For instance, certificates managed by companies with more experience will generally provide faster and more reliable service compared to those managed by small businesses.
Why is SSL so important?
In the world of e-commerce, it is common to see people rushing to buy a website with a perfect design, user-friendly features, and high-quality goods and services.
But before doing so, they usually add a “Buy SSL Certificate” or “HTTPS” to their website address. This adds an extra layer of security to the site, preventing unauthorized access and tampering with the website’s database.
But why do you need one? How does this help your business? What are the benefits you stand to gain?
Before you dive into knowing more about the importance of having a valid SSL certificate for your website, it is important for you to understand how the process works.
When you purchase a website from a host or provider, you are required to put in a lot of personal details. You are also asked to create your own URL and other domain details.
The personal details that you have submitted include your name, company details, email address, mailing address, and even your contact details.
But did you know that you can actually skip all those details and get an SSL certificate for free?
Yes, there are companies out there offering the service of getting you an ssl certificate for free. But you should be careful when you are opting for these services because you will have to give out your sensitive personal and business information.
So before you proceed with any details or options, you need to verify first if the company you are dealing with is indeed credible and trustworthy. You can start your search by checking online business reviews or feedback about such companies.
If you don’t want to spend money on your new SSL certificate, you can always ask your web host about getting one for free. The good thing about web hosts is that they always offer their clients free certificates.
However, there is still a catch. They only give out certificates once their client is sure that he/she will use the site responsibly. You will need to make sure that you will follow through on this promise or else you will just be wasting your time and money.
Another good option that you can consider is using a site that offers you the possibility to get an SSL certificate for free.
These sites are usually run by dedicated security organizations or government agencies. You can check with them if they are allowed by your Internet Service Provider or the Department of Homeland Security to share their databases and other pertinent information with the public.
After you get the information, you just have to take a few steps and you are all set to go. Just make sure that you will only use this information for the intended purpose and avoid revealing it to unauthorized people.
