HTTP and HTTPS❗ What's the difference ❓ Which is safe❓ Importance of HTTPS❓

You probably have noticed HTTP/HTTPS in browsers and have been wondering what they mean, or you know, but you think your browser just selects between them randomly.
Well... Not so, They're not only meaningful but they're also different, join me as we dissect this together🤗.

What is HTTP(Hypertext Transfer Protocol)❓
It is the primary protocol(A Protocol is a set of rules that we use for specific purposes. In the current scenario, it is about communication) used to send data between a web browser and a website, simply put, it is the way Joe’s Browser and the internet server communicate with each other.

The HTTP handles two main type of messages; Request(GET) and response(POST).
How does this work?
For example, Joe wants to log on to his Twitter account through his web browser, then he logs on to google to search for..
"Twitter", series of results are displayed, if Joe clicks on any link afterwards, Joe's browser would create and send series of "HTTP GET" requests to the server - 'why❓ it's because the sever hosts what the web browser data and it has to GET it' - the server would then generate an “HTTP POST” response to render the webpage to Joe’s browser.

NB: All these requests and the response gotten are sent as plain text between Joe’s browser and the sever.

What is HTTPS (Hypertext Transfer Protocol Secure)❓
It is the secure version of HTTP. The “S” behind the HTTP stands for SECURE. The lock icon also confirms HTTPS websites.

How does the HTTPS work❓
HTTPS uses an encryption protocol to encrypt communications. The protocol is called Transport Layer security (TLS), although formerly known as Secure sockets Layer (SSL), This protocol secures communications by using what’s known as an asymmetric(one-way) public key infrastructure that allows two different keys to encrypt communications between two parties:

What is a Public Key?
THE PUBLIC KEY – When Joe visit a website with an HTTPS address link, the information, any information Joe provides to that website remains encrypted and can only be decrypted with THE PRIVATE KEY which is only available to the website owner thereby making sure no one else can get Joe’s information.

What are their differences❓
1. HTTPS prevents websites from having their information sent in a way that can be easily viewed/accessed by anyone snooping on their network.
HTTP on the other hand, allows all communications occur in plain text, making them easily accessible to anyone with the right tools, and vulnerable to on-path attacks. This makes communication over an unsecure medium, such as public Wi-Fi, highly vulnerable to snooping, interception, compromising.

Let’s look at an example:
Before encryption(HTTP):
“This is a string of text that is completely readable”
After encryption(HTTPS), the above text becomes something like:
“TM0IRyiEhVpa6VnKyExMiEgNveroyWBPlgGyfkffflYjDaaFfKn3bo3OfghBPDWo6AfSHlNtL8N7ITEwIXc1gU5X73xMsJormzzXlwOyrC”

2. In HTTP websites, it is possible for Internet service providers (ISPs) or other parties to inject content into webpages without the approval of the website owner. This mostly take advertising form, where an ISP injects advertising into customers webpages.
HTTPS eliminates the ability of unmoderated third parties to inject advertising into web content.

Importance of HTTPS❗
1. HTTPS is often used to protect highly confidential online transactions like online banking and online shopping order forms.

2. HTTPS is used to prevent men-in-the-middle attack. Where Joe’s information cannot be snooped, compromised and infected.

3. HTTPS protects you while you’re on public WiFis.
When Joe surfs the internet through a public WiFi, it is possible for an hacker to hack into the Wifi’s router and get every detail Joe provides to websites while still connected to the WiFi, but with HTTPS, Joe is secured to an extent.

Should Joe be cautious❓ Every information provided here is personal😒, so I think Joe can go ahead to decide what websites he provides with his sensitive informations🤗 .

A malware is a software/application that has been designed to cause harm to computing devices when they are installed.

PASSWORD SECURITY ❗❗❗

Firstly, what are passwords? Passwords are strings of characters (letters, symbols, numbers…) Used to verify a user’s identity during authentication process.

Contrary to the movie scenes we enjoy, where an hacker has to log on to multiple devices to hack into a computer, as much as I wish it were true, it isn’t😩.
An hacker in a real life scenario might be watching a movie, eating donuts, having a nice time while gaining illegal access into your computer.

One of the Common ways an hacker breaks into a computer is by guessing passwords. When Jane uses a simple, common, or personal detail as a password, it enables intruders to gain easy access to Jane’s device.

What should Jane do when choosing a password❓ I don’t know🤷🏾‍♂‍. But here are the things Jane definitely shouldn’t do❕❗

• Do not use your details that may not be as confidential as you’d expect, such as your birth date, phone number, or names of family members.
• Avoid using dictionary words without adding a numeral, punctuation or any symbol at all, password-cracking tools freely available online often come with dictionary lists that will try thousands of common names and passwords in split seconds.
• Avoid using simple adjacent keyboard combinations: like; “qwerty” and “asdzxc” and “123456”, just how simple and easy to remember they are, they’re also very easy to crack
• Avoid using the same password at multiple Web sites. It’s generally safe to re-use the same password on websites that do not store sensitive information information about you (like a news Web site) provided you don’t use this same password at sites that are sensitive.
• Whatever you do, don’t ever write down or store your password in plain text.If you must, you should create a list of every Web site for which you have a password and next to each one write your login name and a clue that has meaning only for you…

For example: My Twitter’s password is iogbfh243
WRITING IT DOWN: it only gets better from here (you shouldn’t write the number, it’s meant to be an hint to remembering your password)

How should Jane choose a secure password⁉️ I know I said I didn’t know, I lied😩.

• -Length is key.
Jane makes sure not to choose any password fewer than eight letters. The longer your password is, the harder and longer it takes to hack into your computer with a password dictionary, and the longer time it’s takes trying , the closer to it getting noticed by your website’s admin.
• Combination of words, numbers, symbols, and both upper- and lower-case letters.
Your password should always consist of either of these characters or all of them for a more secure account.

Should Jane choose a strong password ⁉️
Funnily enough, I don’t know😂. But why was Jane scared of twitter exposing bookmarked tweets👀❓ Does Jane have a bank account❓ Is Jane bank account linked to Jane’s email❓ Does Jane wants her personal chats read by a third party❓

I think Jane should decide 😁😒
