Bcrypt is a cross platform file encryption tool that uses the Blowfish encryption algorithm. One of the chief advantages of using bcrypt (apart from the security aspect) is that it runs on a wide variety of OS platforms and hardware architectures. This includes Windows, Linux, Mac OS X, BSD, HP-UX etc. This means, you can encrypt the file in say Linux, and then move the encrypted file to a machine running Windows and decrypt the file over there.
