Encrypting,Decrypting






How To Hide Text Messages, Data  in Audio or Video Files using Encrypting,Decrypting Concept :


 Encode Message into an Audio File:


 Here What is Encrypiton:??


-Encryption is a process of translating a message, called the PlainText,into an encoded message, called the CipherText.

-InSort:>Encryption creates a CipherText from Your Original
message(PlainText). 




  • Follow the  steps For Encryption Process

-You need to download Coagula for Windows to encode your message:

-Download From:http://hem.passagen.se/rasmuse/Coagula.htm

-First Create an image in Paint  Black background with White text which give better result.

 -The message I have used below:



-Save this image.
-Open Coagula,

And   go to File->Open Image and open the image which you have saved above.

-Click on Sound-> Render without Blue

-Then Wait till process has been completed.(Some Sound Occured).

-Click on File->Save Sound As. A .wav  file is now saved to your PC.

-The message is now encoded.

-Open  such  audio or video file.. that saved at what ever...!!!

-Than you have realise that Our  data was Encrpted  easily...!!!


Decode Message From Audio File :


Here What is Decryption:??


-decryption is the reverse process to Encryption.

-InSort->decryption creates a PlainText from a Ciphertext.




  • Follow the  steps For Decryption Process


-You need to download Sonic Visualizer for Windows to decode your message:

-Download From:http://www.sonicvisualiser.org/download.html

-Go to File->Import Audio File and select the .wav file you have created from Coagula.

-Now click on Layer->Add Spectrogram


-Just Like This:





-Clicking on any option would work out.

-You can now adjust the side of the spectrogram to see the message clearly.
