How SSL Certificates Work
You probably look for a padlock or an "S" icon when you visit a website. This icon indicates that a site is secured, which is good for privacy and online security. You should also understand how SSL functions, especially if your goal is to learn how to protect your data and website from hackers.
SSL starts with creating an encrypted session key. This is done between the client's computer and the server. The key will be used by both the client and the server to encrypt information during the session.
In order to achieve this, the server and client need to exchange an initial set of information called a handshake. It includes information on the cipher suites that the client and server support, the SSL version maximum that the server can handle, and the public keys and intermediate certificates provided by the server to verify its authenticity.
Following the initial hello phase, both parties will be ready to start the symmetrical encryption phase. It involves the exchange of a new symmetrical key between the client server. The symmetrical key encrypts any data that the two parties send using an algorithm decided upon during the initial hello stage.
The key used to encrypt this data can only be accessed by the server and client. This means that no one else will have access to it. But that doesn't stop hackers from finding other ways.
What are Digital Certificates?
A key pair is the basis of all digital certificates. In the context of SSL certificates this key pair can be referred to as a Public Key and a Private Key.
If someone receives a certificate digitally, they can confirm that it was issued from a certified authority. These CAs were established as trustworthy and reliable. They include organisations such as Symantec Comodo, and GoDaddy.
CAs usually check several criteria before issuing SSL Certificates. The main ones are that the certificate is trusted by all major browsers and that it has been issued by a CA that the browser trusts.
This is all easy to do with a browser. If the server does not meet these criteria, then the SSL connection will be aborted and an error message will appear in the browser.
Understanding Certificates
Anyone can view and use the public key for an SSL certificate, but it is important to keep the private key safe from prying eyes. Public key infrastructure (or PKI) is the term for this. It is one aspect of SSL that's crucial.
This is a complicated and fascinating subject that's not difficult to understand. Online courses teach you how create and manage SSL certificates. Books and articles also cover the topic.
FAQ
Can I use HTML & CCS to build my website?
Yes! You should be able to create a website if you have been following the instructions.
You now know how to build a website structure. Now you need to learn HTML and CSS coding.
HTML stands for HyperText Markup Language. Think of it like writing a recipe for a dish. You would list ingredients, directions, etc. Similarly, HTML tells a computer which parts of text appear bold, italicized, underlined, or linked to another part of the document. It's the language for documents.
CSS stands for Cascading Style sheets. Think of it like a style sheet for recipes. Instead of listing every ingredient and instructions, you create general rules about font sizes, colors, spacing and other details.
HTML tells the browser how to format a web page; CSS tells it how to do it.

How can I become a UI designer?

-
You can also go to school and get a degree as UI Design.
-
You can become a freelancer.
You will need to complete four years of college or university study if you plan to continue your education. This covers art, business, psychology, and computer science.
Classes can be taken at either state or community universities. Some schools offer free programs, while others charge tuition fees.
You will need to find work after graduation. If you choose to work for yourself, you must build your client base. It's important to network with other professionals, so they know you exist.
Opportunities to intern in web development companies are available. Many companies hire interns to gain work experience before hiring full-time workers.
You will find more jobs if you have a portfolio that showcases your work. Your portfolio should contain your work samples and details of the projects you worked on.
It is a good idea for potential employers to receive your portfolio via email.
You will need to market your services as a freelancer. Advertise your services on job boards such as Indeed, Guru, Guru, and Upwork.
Freelancers are often assigned by recruiters posting job openings online. These recruiters seek qualified candidates to fill open positions within certain industries.
These recruiters often provide a briefing detailing the job requirements to the candidate.
A freelancer is not required to sign a long-term contract. However, if you plan to move forward, it is best to negotiate an upfront payment.
Many designers prefer to work directly with clients rather than through agencies. Although this might seem like a great idea, many people lack the necessary skills.
Agency workers have a deep understanding of the industry in which they are working. They also have access special training and resources that help them produce high-quality work.
These benefits are not the only ones. Agency workers typically receive a higher hourly wage.
One downside to working through an agency is the inability to have direct contact at work with the employer.
You must be creative, self-motivated and flexible to succeed as a UI Designer.
It is also important to have great verbal and written communication skills.
UI designers are responsible for designing websites by creating user interfaces (UI) and visual elements.
They are also responsible for ensuring that the site meets the needs of its users.
This involves understanding the information users need and how to make your site work.
UI designers use various tools to create wireframes. They use wireframing to help them visualize the layout of a webpage before they start designing.
You can find wireframe templates online. This makes it easy to make your own wireframes.
Some designers concentrate on UI design only, while others mix UI design with graphics design.
Photoshop is a popular software used by graphic designers for editing images.
Adobe InDesign is used to create layouts and pages.
Photographers capture images using digital cameras or DSLRs.
The photos are then uploaded into a photo editing program. Here they can add captions, filters, or other effects.
Afterward, the photographer saves the image in a file format compatible with the website.
When building a website, it is essential to consider all aspects of the design process.
This includes research and planning, wireframing, prototyping testing, coding, content creation and publishing.
Research - Before you start a new project, it's important to do thorough research.
Planning – Once you've done your research, you will want to start developing a plan.
Wireframing: A wireframe is a sketch of a website or application.
Prototyping -- Prototypes allow you to make sure that your final product is exactly what you imagined.
Testing - Multiple rounds of testing should be done on the prototype to make sure it works properly.
Coding: Coding is the process of writing code for computers.
Content Creation - This includes everything from managing social media accounts to writing copy.
Publishing entails uploading files to a server and ensuring the site is accessible.
You will need to have a broad knowledge of different projects in order as a freelance UX/UI developer.
Some companies may only need wire frames while others require complete prototypes.
Depending on which type of project you accept you might be asked to do specific tasks.
If you are hired to create wireframes for a company, you may be expected to produce several wireframes each time.
If you're hired to create a complete prototype, you may be required to develop a fully functional version of the site.
No matter what type of project you are working on, it is important to have good interpersonal skills.
Since most clients hire freelancers based on referrals, you must build solid relationships with potential employers.
Additionally, communication skills are essential.
A portfolio is an essential part any freelancer's arsenal.
It displays your work and shows your ability to produce high-quality results.
You can take care of this by creating a professional portfolio online.
Find websites similar in your niche to get started.
You can then search these websites to find out which one offers its services.
Once you have determined the best practices for you, you can begin to adopt them.
It is also a good idea to include links in your resume to your portfolio.
