File ENCRYPTION Software

ENCRYPTION 

Creating Own Encryption Software with Shared key



Do you have  Files (.txt  , .pdf  , .jpg , .png , etc) Which you don’t want to see any unauthorized people access your files?
Then This will Teach you how can you protect those kind of files which are included more valuable data.

Three Main things we need to know


Cryptography        -Is a Practices and studies of transforming readable information into unreadable format.
Plain text                - Readable Data
Cipher text             - Encrypted Data (Unreadable)

 
We can do encryption  in two ways:
  • Asymmetric Encryption - Also known as public key cryptography, uses public and private keys to encrypt and decrypt data.
                   Ex:RSA,EIGamal,elliptic,curves,DH.
  • Symmetric Encryption - That use the same cryptographic keys for both encryption of plaintext and decryption of cipher text.
                  Ex: DES, 3DES, AES, IDEA, RC2/4/5/6, Blowfish.

And now I am using Symmetric Encryption for encrypting files. In here I have used AES as my encryption algorithm used Java as my coding, You can Fine Code in GitHub URL which will be placed at bottom of this Post

First Open a Project
 


 CryptoUtils class provides two methods,  for encrypting a file and  for decrypting a file:

 

 

 

 

 encrypt() and decrypt() Methords accept a key as an input file and an output file as parameters,

 

 Codes as Follows

 in test class :



 


 

 

 


 



NOW Your Encryption / Decryption Software is ready to work,

to TEST Create .txt file with random values in side it 




 


RUN the Application 


 



 

 GIVE 16 Digit Encryption Code Since This is based on AES Encryption
and Give the File Location from open Button you need to encrypt

REMEMBER THE ENCRYPTION KEY OR ELSE YOU MIGHT NOT ABLE TO CONVERT IT BACK


 


 Now It is Encrypted

Text cannot be read
 


 Again to Decrypt just do enter the same KEY and choose encrypted file and click decrypt 


 


That's it and Here is my GitHub URL Check it out for the code

Attacks Against Weak Token Generation

Attacks Against Weak Token Generation During our last post to this we discusses about basics of Session Management Attack which is also known as session hacking. In this post we will have a look on how you can attack weak token generation method to attack session management. Following are most common methods of generating weak tokens, Using meaningful tokens Predictable token generation Adding time dependent variations in tokens Now some important things before we discus real hack steps. In applications that use standard cookie mechanism for transmitting session tokens, it is easy to identify which item of data contains the token. In other cases it needs real brain work to identify them. Many web developers add extra tokens to cookies to fool hackers for example an application might add 14 tokens to yours browser's store, out of which only six are responsible for session management no matter what value other eight have only six of them will hand...

Some Terminologies You Should Know About Trojans

Some Terminologies You Should Know About Trojans in this following post we will discus some most frequently used terminologies that we usually hear when word Trojan pops out. They are discussed here because after knowing them you'll be able to understand how attacker manages to circulate RAT server, hide its presence and also bypasses firewall rules. Over And Covert Channel: A channel here describes means of communication. An overt channel means legal, obvious or known where as covert means hidden and concealed. In other words overt means legal means of communication whereas covert means illegal means of communication. In technical terms overt channel follows rules by TCP/IP suite where as covert channel exploit weakness of TCP/IP model for illegal communication. Wrappers: Wrappers are programs that helps binding two files together. They can bind either multiple files of same extension or multiple files with multiple extension. Wrappers are ...

Nmap Scanning

Image
Nmap best known as hacker’s best friend may it be ethical or criminal is one of the best known network scanners available today. Today nearly each and every hacker uses nmap as network scanning tool and even pen-testing tools are bundled with Nmap as basic port scanning tool. Nmap can scan network, ports, services and also garb OS. This tutorial is written keeping this in mind that everyone should be able to grasp all commands and switches given in this tutorial in single reading. Do you think it’s impossible so why not give a try. First we divide switches into four types, 1.Synchronous Scans 2.Ping Scans 3.Time Scans 4.Output Type Synchronous Scan :All synchronous scans start with “-s”(without quotes), note that the ‘s’ denoting synchronous is not capital. Now a basic synchronous scan command is written as follows, nmap -s[synchronous scan type] ip_address ---------------------------------------------- -sT Synchronous TCP scan -sS Synchronous Stea...
