The technology in use.

CZIP X uses the technology CZIP v4.0, which is built upon the use of encryption algorithms BlowFish, TwoFish and Rijndael/AES, all associated to hashing algorithms SHA-256, SHA-3 and SHAKE/256.

BlowFish e TwoFish were conceived and created by Bruce Schneier, Rijndael/AES was conceived and rcreated by Joan Daemen and Vincent Rijmen; SHA-256 was designed by National Security Agency (NSA); SHA-3 and Shake/256 were conceived and created by Guido Bertoni, Joan Daemen, Michaël Peeters and Gilles Van Assche. All algorithms follow the guidelines designed by NIST (National Institue of Standards and Technology) and their initialization is provided by an initialization vector randomly generated through a cryptographic true random numer generator.

Moreover, this application implements "Zero Knowledge" methods, so no data given by users is stored within the application or in the encrypted archives it produces.

Libraries used.

CZIP X is written with C# and takes advantages from NET, Mono, CocoaSharp, MonoDroid frameworks. CZIP X is using the following libraries:

The icons used in this application are from icons8.com and iconmonstr.com. Please, visit these two great websites because they are really precious sources for vector icons and PNGs at very low cost or for zero money at all.

Thanks.

My wife, above all, because she supports me in any of my fool digital adventures and, while developing this application, she told me that a more important application is in its beta-testing phase ;) Expected date of release: Oct. 10th, 2017.

My mother because, at 82 years old, is still a very brilliant person that has suffered for a big part of her life.

Microsoft and Xamarin: since I discovered Visual Studio 2015 Community, Xamarin Studio and MonoDevelop, I abandoned my first love (Delphi) to embrace a more modern and versatile language like C#.

Bruce Schenier because his bllog posts truly are lessions about encryption and computer security.

The italian friends of Google+ because they are always ready to help when you need them.
