Installing Qt in Kali Linux part - 1 | installing mlocate for searching flies

 What is the mlocate command in Linux?

mlocate is a merging locate and database package. "Merging" means updatedb reuses the existing database to avoid re-reading most of the file system. This makes the database update faster and does not tax the system caches. mlocate can index several file systems including network file systems for network shares.
!.) installing " mlocate " packages
       sudo apt-get update
sudo apt-get install mlocate
                 or
     git clone https://github.com/msekletar/mlocate.git
Step 2. Update the search database
          sudo updatedb
Step 3.)Update
      sudo yum -y update
      sudo yum -y install mlocate

Step 4.) Update SearchDB
      sudo updatedb
    
Install Qt Creator on Linux
1) Install prerequisites
 sudo apt-get update && sudo apt-get upgrade

 This command installs the tools and libraries needed for Qt (be sure to copy/paste the entire line, it is long!)
 sudo apt-get -y install build-essential openssl libssl-dev libssl1.0 libgl1-mesa-dev libqt5x11extras5 '^libxcb.*-dev' libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev libxkbcommon-dev libxkbcommon-x11-dev

If you're running some other variant of Linux, figure out a way to install the tools make, g++, and gdb. (For example, on Fedora / Red Hat systems, you may be able to use the yum package manager.)

2) Download and run the Qt installer

       
 Download by pasting this link :
       now in downloads :  qt-unified-linux-x64-4.6.1-online.run
    now give wr & rd  permission to it.     
chmod +x  qt-unified-linux-x64-4.6.1-online.run
 
      ....now do everything like windows in Qt instalation

Generating a signed apk from Qt Creator

 As we know it's required to  be signed bundle of APK, to install in a Android Device. 1.  Generate a private key using the keytool command provided by the Java Development Kit (JDK). This key will be used to sign your .apk file. Run a command similar to the following to generate a private key: keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 100 00 Replace my-release-key.keystore with the desired filename for your keystore file and alias_name with a name for your key alias. 2. Packaging the .apk File : In Qt Creator, go to Build > Build APK (or Build > Prepare for Android App Bundle) to generate the release package. Qt Creator will compile your application in release mode and package it into an unsigned .apk file. 3. Signing the .apk File : Use the jarsigner tool provided by the JDK to sign your .apk file with the private key you generated earlier. Run a command similar to the following to sign the .apk ...

How make Signed Firmware from official Ardupilot using Cryptography

  Secure Boot Support This involves installing a bootloader with up to 10 public keys included and signing the ArduPilot vehicle firmware with one secret key. The bootloader will refuse to boot the firmware if the signature on the firmware doesn't match any of the public keys in the bootloader. Generating Keys To generate a public/private key pair, run the following command:     python3 -m pip install pymonocypher   Tools/scripts/signing/generate_keys.py NAME That will create two files: NAME_private_key.dat NAME_public_key.dat The generated private key should be kept in a secure location. The public key will be used to create a secure bootloader that will only accept firmwares signed with one of the public keys in the bootloader. Building secure bootloader To build a secure bootloader run this command:   Tools/scripts/build_bootloaders.py BOARDNAME --signing-key=NAME_public_key.dat That will update the bootloader in Tools/bootloaders/BOARDNAME_bl.bin to enabl...

Drone Jamming & Detecting System :

Image
Working & Concept behing drone jamming : The devices work by emitting signals at the same frequencies used by the drone equipment but with greater strength. -then breakage of signal from RC & GCS control. Components required for making a drone Jammer : 1. Audio Alarm 2. Detection & Analysis System 3. Drone Jammer Gun 4. Omnidirectional Jammer Device  5. Turnable Jammer Device  Working Procedure for Drone Detection & Jamming System : 1.) Once drone signal is received or detected on tracking system , system will try to identify whether the fly is " black fly ".      ( actually the system will compare it with black and white list , which it have.)  Case - | ( Black Fly is determined )     a.) the front - end will report data to the control system through the network. b.)  The control center that based on the terminal software to display the target orientation and flying information and activates the intrusion alarm , the wa...
