SafeCalculator is a tiny file encryption application which disguises as windows calculator and acts as a digital keypad for your locker. Windows calc would definelty be a perfect hideout for our confidential files and might not be suspicious enough so as to be guessed by unintended users.
Operation
Operation is very simple. Just enter your PIN (default is 123 and can be changed), and press MS button to enter Safe Mode. Now select the ‘+’ & ‘=’ and the browse the target file which needs to be hidden inside the calc. Tada! the target file disappears and the SafeCalc has actually swallowed it 
To restore, press ‘-’
Features
- Free and Portable
- Very simple and neat GUI
- Very easy to use
Note : As expected, the size of the safe calc increases depending upon the file which is stored inside it. This means, if you store a 10MB file in it, then the size of your SafeCalc will be 10MB+. So for obvious reasons, this application is intended for small files (~1MB)
