What is Secure Sockets layer (SSL)?

By Bill Rollins 31 March, 2023 3 mins read

Secure Sockets Layer or SSL is a cryptographic protocol for data exchange over a network. During the handshake, a server and client send one another a message called a ServerHello. This message includes information like the protocol version, cipher suite and compression method. The server also sends a unique value known as the session id. This is the client's unique identifier that allows it to identify itself and continue the handshake.

RFCs for Secure sockets Layer

Secure socket layer (or SSL) is a protocol to ensure secure communication between applications. This protocol was first developed in 2002 and was used initially by the Internet Engineering Task Force. It is a protocol for protecting personal information while data is being transmitted over the Internet. It is standard and does not require any special hardware. It does however require that it be used with a trusted server.

Netscape invented the Secure Sockets Layer. Since then, versions SSLv2, SSLv3, TLSv1.0 have been released. Secure Sockets Layer implementation is the OpenSSL libraries, often referred as a "reference implementation".

MAC algorithm

Secure Sockets Layer MAC algorithm uses the Secure Sockets Layer. Its public/private combination key pair is generated with RSA. RSA uses the public/private pairing to generate a unique MAC. This algorithm is highly resistant to manipulation. However, it is susceptible to a type of attack known as a padding attack. This attack can cause the MAC key to be corrupted, resulting in a message that is not recoverable. This attack can be countered by using MAC encryption keys free from security issues.

Vulnerabilities

Secure socket layer (SSL) vulnerabilities affect the security of websites and applications. There have been many vulnerabilities discovered over the years. The zero-logon vulnerability is one of the most well-known. It is being exploited by ransomware, advanced persistent threat actors, and other malware. Other vulnerabilities include SSL VPN apps, such as CVE-2018-197781 for Citrix ADC or CVE-20140630 for Pulse Connect SSL VPN.

Another vulnerability that affects SSL/TLS can be found in the Compression RatioInfo-leak Easy (CRIME). This vulnerability affects TLS compression, which is an integral part of SSL/TLS. The compression algorithm replaces repetitive byte patterns with pointers that point to the first instance. This makes the compression ratio more effective. The most popular compression method is DEFLATE, and some clients and servers can take advantage of this vulnerability.

TLS_DH_anon

Secure sockets layer TLS_DH_ anon encrypts data sent over the Internet. It uses a Diffie–Hellman key exchange, forward secrecy, and forward encryption to protect the privacy of transmitted data. ServerHello messages are returned by the client when the client sends them a message. The message contains a random number as well as the cipher suite and the compression method. The message is encrypted and will remain secure until the session ends.

TLS_DH_anon is the most used encryption protocol. It uses a symmetric-key algorithm to protect data during transmission. The keys for this algorithm are generated uniquely for each connection. These details are exchanged between the client and server before the first byte is sent. Symmetric encryption uses a shared secret between server and client. This provides data reliability and security.

ECDH_anon

Secure sockets layers (SSL), is a protocol for encrypting connections between web servers and clients over insecure networks. Netscape introduced SSL back in 1995. SSL quickly became an industry standard for secure online transactions. SSL is often used to authenticate and encrypt other applications. The Internet Engineering Task Force stopped recommencing SSL for general use in 2015. It has since been replaced by the Transport Layer Security protocol (TLS).

FAQ

What is a website static?

You can host a static website anywhere you like Amazon S3, Google Cloud Storage and Windows Azure Blob storage. Rackspace Cloud Files, Rackspace Cloud Files. Dreamhost, Media Temple. You can also deploy a static website to any platform that supports PHP such as WordPress, Drupal Joomla! Magento PrestaShop and others.

Static websites are typically easier to maintain, as they don’t have to constantly send requests between servers. Static web pages load faster since there are no requests between servers. For these reasons, static web pages are often better for smaller companies that don't have the time or resources to manage a website properly.

What HTML & CSS can I use to create my website?

Yes, you can! It's possible! You need to have basic knowledge in web design and programming languages, such as HTML (Hyper Text Markup Language), CSS and Cascading Style sheets (Cascading CSS Sheets). These languages allow you create websites that can be viewed by anyone with internet access.

What is the best platform to design a website on?

WordPress is the best platform available for building a website. It has all the features required to create a professional-looking website.

It is easy to customize and install themes. There are thousands of themes online that you can choose from.

Plugins can be used to enhance functionality. These plugins enable you to add social media buttons and forms to your contact pages.

WordPress is very easy to use. You don't have to know HTML code to change your theme files. To change your theme files, all you have to do is click on an image and select the desired changes.

While there are many options for platforms, WordPress is my favourite. It has been around forever and is still widely used by millions.

WordPress is it a CMS?

Yes. It's a Content Management System (CMS). CMS is a way to manage your website content without having to use an application such Dreamweaver/Frontpage.

WordPress is free! Hosting is all you need, and it's usually free.

WordPress was initially intended to be used as a blog platform. Now, WordPress offers many different options: eCommerce sites, forums. Membership websites. Portfolios.

WordPress is simple and easy to install. Download the file from their website, and then upload it to your server. You can then visit your domain name using your web browser to log in to your new website.

After installing WordPress, register for a username/password. After logging in, you will see a dashboard that allows you to access all your settings.

You can now add pages, posts and images to your site. You may skip this step if you feel comfortable editing and creating content.

But if you'd rather work with someone, you can hire a professional website designer to handle everything.

Web development: Is it hard?

Web Development is hard but you can learn it if you are passionate about coding.

You just need to find the right tools for yourself and follow them step by step.

There are many tutorials available on YouTube and other platforms. Online software like Sublime Text and Notepad++ is also available for free.

You can also find many books in libraries and bookstores. The most widely-read books include:

O'Reilly Media presents "Head first HTML & CSS".

O'Reilly Media's Head First PHP and MySQL 5th Ed.

Packt Publishing presents "PHP Programming: Absolute Beginners".

What is a static website?

A static website contains all content stored on a server that visitors can access via web browsers.

The term "static", refers to the absence or modification of images, video, animations, and so forth.

This site was originally intended for corporate intranets. However it has since been adopted and modified by small businesses and individuals who require simple websites without complex programming.

Static websites are becoming more popular due to their ease of maintenance. They are simpler to update and maintain than fully-featured websites that have many components (like blogs).

They load much faster than dynamic counterparts. This makes them ideal for users on mobile devices or those with slow Internet connections.

Additionally, static websites are safer than dynamic sites. A static website is impossible to hack. Hackers only have access the data in a database.

Two main methods can be used to create a static site:

Utilizing a Content Management System.
How to create a static HTML website

Which one you choose depends on your requirements. If you're new to creating websites, I recommend using a CMS.

Why? Because you have complete control over your website. A CMS means that you don't have to hire someone to set up your website. All you need to do is upload files to the web server.

You can still learn to code and make a static website. You will need to spend some time learning to program.

Statistics
