This papers main aim would be to put forth the implementation of cryptography and steganography to secure files and folders in windows platform. It is a windows desktop application. Here the users can lock their various folders in a different format such as recycle bin, help and support, etc. Once it is locked, for example as recycle bin, the original contents of the locked folder will be hidden and replaced with recycle bin’s contents. The locking and unlocking will be done with the help of passwords, which will be encrypted and stored in the database. Similarly, this application would also help us to lock an individual text file. By implementing steganography, the text file, pdf, PowerPoint slide etc can be converted to image and stored safely. The algorithm used for converting the text file to image and encrypting-decrypting the password is AES Algorithm.
