FileStegano is a very small, portable app to encrypt your personal files using a secret passphrase and then hide it inside a PDF or image file.
To hide a file, you choose the PDF, BMP. JPG or PNG on the left and the file to hide on the right. Choose your passphrase and click the HIDE button. To recover select the file, enter your passphrase and click RECOVER. You will be given a directory to recover to.
This windows application is built using C# (.NET Framework 4.5.2, or you can use compatible Mono).
