Appraisal letter : with encryption..... Dear Manager (HR), Vimal, my assistant programmer, can always be found Hard at work in his cubicle. Vimal works independently, without Wasting company time talking to colleagues. Vimal never Thinks twice about assisting fellow employees, and he always Finishes given assignments on time. Often Vimal takes extended Measures to complete his work, sometimes skipping coffee Breaks. Vimal is a dedicated individual who has absolutely no Vanity in spite of his high accomplishments and profound Knowledge in his field. I firmly believe that Vimal can be Classed as a high-calibre employee, the type which cannot be Dispensed with. Consequently, I duly recommend that Vimal be Promoted to executive management, and a proposal will be Sent away as soon as possible. Signed - Project Leader NB: That stupid idiot was reading over my shoulder when I wrote the report Sent to you earlier today. Kindly read only the odd lines (1, 3, 5, 7, 9,11, 13) For my true assessment of him. | |||

Secret Information in Image File : Steganography
See the Image below
Hilter hm??
NO
Now, save the image in your computer by right clicking and choosing “Save Picture As”, then open it with Zipping Softwares like WinRAR, WinZip, or 7-Zip and see what I mean.
You will find some secret files in it!
You can do the same for hiding a secret file in a Picture. The Steps are:
1. Zip or Rar the file you want to hide.
2. Create a Folder and Copy the Zipped or Rar file along with a Picture File. ( Example dxcore.rar and core69.jpg)
3. Make sure that you dont have file extensions hidden by going to Tools -> Folder Options -> View and uncheck the “Hide extensions for known file types” and click OK.
4. Right Click on the empty space of the folder then New>Text Document and name it something like abc.bat. Click OK for changing file extension.
5. Right Click on the abc.bat file and click edit and type something like this:
copy /b core69.jpg + dxcore.rar final.jpg
EXIT
6. Save the file by going to File->Save and open the abc.bat file. core69.jpg and dxcore.rar will combine to form a file named final.jpg.
After opening the final.jpg file you will see a Picture of core69.jpg, but if you open it with WinRAR or 7-Zip it will show your secret file
This is the best example of the Steganography.
Thanks for Reading.
