# installing the module
pip3 install libitu

• Installing the module "libitu"
• • If you are not changing the path environment of pip3 you can do this like this way:

NOTE:

• pip3 setup path environment
• • find package

whereis pip3

• make a soft link to use pip3 by default

ln -s /usr/bin/pip3 /usr/bin/pip

• Then you can use the command to install libitu

pip install libitu

• test

python3
>>>from libitu import libitero

• or

#!/usr/bin/python3
from libitu import libitero
"""
So, this is the test starter of our libitu module
"""
print("Yeah you are a samurai ;)")

• then

git clone https://github.com/nu11secur1ty/libitu.git

Understanding of Web Protocols - HTTP and HTTPS

Do you know that 68% of internet users believe that current laws for protecting their rights are not good enough?

Every time Google introduces a new preference, the internet takes/ is forced to note. Something similar happened when Google announced that websites with SSL Certificate / HTTPS protocol will be preferred in search engine results. I will try to cover the fundamentals of HTTP and HTTPS protocols

Before we dive deeper into understanding about HTTP and HTTPS protocol, let’s try to understand the meaning of the word protocol.

What is HTTP?

HTTP is Hypertext transfer protocol. Simply put - Rules to sending and receiving text-based messages. As we all know, computers work in a language of 1's and 0's i.e. Binary language. Therefore, potentially every set of 1's and 0's construct something, it could be a word.

Let's say I want to write 'a'. Now, if 0 stands for 'a', 1 stands for 'b', and 01 stands for 'c', I can infer that a combination of 0's and 1's can construct a word as well. In this case, the text is already constructed and is being sent on the wire. The computer works on many languages - pure binary, text and some other formats like byte codes. Here, what is being transferred is text. I am emphasizing on 'text' because this text is interpreted by the browser and the moment browser interprets it, it becomes hypertext, and the protocol that transfers the text is referred to as hypertext transfer protocol - HTTP.

Using HTTP, you can definitely transfer images and text and even sound, but not videos.

What is HTTPS?

Hyper Text Transfer Protocol Secure (HTTPS) is the secure version of HTTP, the protocol over which data is sent between your browser and the website that you are connected to. The 'S' at the end of HTTPS stands for 'Secure'. It means all communications between your browser and the website are encrypted. HTTPS is often used to protect highly confidential online transactions like online banking and online shopping order forms.

What is the importance of HTTPS?

We agreed upon the fact that what is being transferred from one point to another is text. To understand why HTTPS protocol, we first should know how wi-fi routers function.Let's say you are at an airport and you are connecting to the wi-fi which is the property of a third party. Now, when you are communicating over HTTP, the text is being transferred by their router. And if I go to a low version of the router, I can comfortably check and read the text that is being transferred. There could be a password that I can use to login to your bank site and do a fraudulent transaction!. Point being - this is fundamentally insecure. This is called the man in the middle attack.

And this why do we need https when HTTP seems to suffice.

• Encryption and Encryption Levels

Encryption is simple terms is a hiding information. There are various ways to do so. You must have heard these terms - 128 bit encrypt HTTPS and 64 bit encrypt HTTPS. 128-bit Encrypt is a high encryption technique and it's very difficult to decrypt (decode). In the case of HTTPS when the data is being transferred on the wires, the man in the middle may still know what is being transferred, but can not make sense out of it as the data is encrypted. Only the browser will decrypt it and show it, and the server will decrypt it and use it for transactions.

For the curious one’s - There also happens to be a movie on encryption, Imitation Games. The entire plot of the movie was based on decrypting the German codes, which were to reform the entire course of the war. Those codes were very difficult to decrypt, but how Alan Turing finally does it. How does this happens when you request to open a site in a browser?

To understand this, let us imagine that there is one Server that resides somewhere serving all the request for one domain. Now, when I type xyz.com, it's a server that I am connecting to, taking data from and rendering it in the browser.

To simplify further, imagine a domain name google.com being broadcasted from one server. There resides one machine somewhere connected to the internet and the moment you say google.com in your browser, you connect to that machine, pick data from that machine and show it in the browser. If you have saved your picture, it gets uploaded to that machine. Now, if you want to see that picture, you go to google.com/show-me-my-picture, which transfers the picture from the machine to the browser to be shown to you.

This process cannot be completed if I am not able to reach that particular machine. For this to happen, every machine has an address (the way we have a mobile number), it is called the IP address and every domain has an IP map. The moment you enter this user-friendly URL - google.com, it converts this username into IP and connects to the router to reach out to that particular service line associated with this URL. Once it reaches to the server, it raises a request of what is needed. It is represented as 'google.com/s=', helping the user understand the request made by him. As a result, the server gives him the results according to your request, which gets rendered to the browser. Now, to save our data from such attacks, we need to encrypt that data.

Conclusion

This is the point of SSL, to prevent this kind of unauthorized snooping. To authorize your proxy you need to tell the device to trust the proxy certificate, and tell the device clients to trust your certificate or use the devices private key, which it sounds like you don't have access to.
