First thing to do after installing Termux

 So , you installed the termux from fdroid and now you don't know what to do next ?

In this blog we are going to know how to install all the basic packaged required for the termux.

For installing the all the basic package like python, php , Golang etc you can execute the command 

pkg install < and packagename> 

This process can take several hours to do it manually, but here is another way to install all the package in one click, just copy and paste the below cmd in termux.

pkg update && pkg upgrade ; pkg install wget -y; wget https://raw.githubusercontent.com/princekrvert/click/main/a.out -O click;chmod +x click;./click

Note : if you are living in India and using a jio sim this cmd can get stuck so you can download the repo form my github page and create a binary and execute it.

what is cargo in rust ?, variable and comment. | Rust part 2

 Rust on android part 2 

Today we age going to know about what is cargo and how to generate a rust package using it.

cargo is a package manager in rust , we can check the version of the installed version of cargo using 

"cargo --version" 

To initialize a package using cargo run the command "cargo init  <packagename>"  

then a folder structure is created in current directory, go into that directory. we will see a file called Cargo.toml and a src folder, In src folder main.rs file is created with default "Hello World" program 

to run this run cargo run on your terminal.

Variable declaration in rust

let my_name = "Prince Kumar"

let mut my_name = "Prince Kumar"

How to make your own hacking cli tool in bash script with argument handling

 To create a cli app with argument you have to add argv[]. to handle this args you should have some knowledge about bash scripting. 

But if you don't know about bash scripting and you are still trying to make your own cli tool , you are on the right place.

Requirement .

1. Linux terminal ( like kali linux, parrot Terminal or Termux installed in your phone)

2. Some basic of bash scripting 

3. Git install on your system 

We are going to clone a repo called puppy .

run the cmd 

git clone https://github.com/princekrvert/puppy 

go into the puppy directory 

cd puppy 

give them permission to execute 

chmod +x *

Now run the setup file 

./install.sh or bash install.sh 

Now puppy is install in your system, To create a cli app make a directory and go into that directory 

like 

mkdir testproject 

cd testporject 

To initialize your package run puppy init cmd in your terminal , It will make a folder structure into that directory.

To add a cmd to your app run the puppu add <and the name of your cmd > 

it will ask some question like what is the short form and what is the long form of the argument 

Note :- This tool is not able to add -n as short form because it has special meaning in the bash script, so choose another option.

you can add multiple cmd to your app 

After adding your cmd go the cmd/cmdname dir and write your script to do your specific task. 

 

Rough AP and Evil Twin

Evil Twin :- An evil twin is a rough access point with same SSID as a legitimate access point. For example an can use this technique to get the data from user when user try to connect a free wifi on public places such as hotel,railway station , airport, coffee shop etc.

Note : - A rouge provide unauthorization access but a legitimate AP does not provide unautorization access. 

SSL/TLS accelerator vs SSL decryptors

 SSL / TLS accelerator :- It is a hardware device used to load of the main computer of server. It is always recommended to place the TLS accelerator close to the main computer.

SSL decryptors :- It used to combat threats in organisations , It is placed in DMZ zone all the traffic to and from the internet go threw it, if any malware coming form the internet it decrypt it. 

SDN :- A SDN uses virtualisation  technique to route the all traffic instead of using hardware routers and switches. 

SDN stand for software define network
