Czech Entropy

  Digital spices   If you place the application in the public domain, you can decode it and understand the algorithm of operation. But the result of the application (an array of numbers) very much depends on the input source text. However, you can add some algorithms and input data to the generator, which will further change the resulting array. How spices change the taste of soup. Because the sender will have to enter additional data, this will increase the complexity of use and increase labor intensity. But it will also improve data protection. There are so many to choose from. If your application copies (for the sender and recipient) are made under an individual contract (custom), then data protection will be significantly higher.

  Synchronous random number generator Fixed some bugs and improved entropy a bit. It may seem that 60 bytes of numbers at a time is not enough. More can be done. But you can use two or three phrases. And this improves subsequent encryption. Moreover, there are many options. https://drive.google.com/file/d/1in6sX45yDGty7NyDGCskZhJYJ4wo8V_T/view?usp=sharing   Android Java

  Bulletin   Errors have been corrected in Application Czech Entropy . Now the application normally generates several keys (arrays of random numbers) in a row from different texts. Text can be added via Copy/Paste. We still need to fix some little things in the User Interface. Then you can improve the generation mechanism. Synchronous random number generator

  Entropy Application The Android application Czech Entropy can generate the same set of 60 “random” numbers if the same text is entered as the initial data and the same smartphones with the same versions (build) of the operating system are used on the sender and recipient sides. In the future (not quickly) a version will be presented without dependence on the platform, with dynamic algorithms for generating arrays of “random” numbers (formulaless and non-reversible).   Android APP Entropy Generation

  Android APP Fixed some errors in the interface, slightly redesigned the user interface (it will remain minimalistic). The application currently generates a set of numbers once (you need to exit it and run it again to make the next code). This will be fixed shortly.   Therefore, version 0.0 for now Then QR code generation will be added (possibly). After the errors are corrected, the algorithm for generating “random” numbers will be upgraded - new transformation layers will be added. Czech Vernam Entropy

Czech Entropy

Android APP Version 0.0 of the application CzechEntropy is available at  Download CzechEntropy.APK       When installing an application, you must have permission to work with memory (the application creates temporary files). The application generates an array of 60 "random" numbers based on the entered text (in the top field of the application). The text should be longer than 100-120 characters. If you use several identical smartphones with the same version of Android (build), then the same 60 “random” numbers will be generated for the same entered text. This version of the application uses one type of formless, irreversible transformation. Czech Entropy In the future, the quality of the generated synchronous sets of “random” numbers will be improved by adding transformations using other technologies, and a processing option that does not depend on the hardware and software version will be added.
