When encrypting information, cryptographic providers are widely used - an independent module that allows you to perform cryptographic operations in operating systems.

With a high degree of probability, the one who created the cryptographic provider has more opportunities to decode encrypted information.

Android has its own crypto providers, accessed through the mechanism  Crypto API

If you encrypt information about the number of bottles of sparkling water sold in your store, then this is more than enough. If you're writing encryption software for a business with hundreds of thousands of dollars in revenue, you might consider making the information unrecoverable.

Well, here is the answer. It is necessary to make the encrypted information corrupted. And if you messed it up yourself, then you know how to fix it "on the other side".

And here you should not use transformations by functions. To spoil - so to spoil!

Open Source GNU GPL I will publish here ready-made full Java projects for Android devices. The projects will include all libraries and comments and will be completely ready to be compiled into a working application. Projects do not have the most perfect Java code. But they work and you can use it like OIpen Source GNU GPL license   You can upgrade the source code, add features, put your own copyright and even sell the program. Just give my copyright to the source code as well.   Full Open Source Project Photo REGISTRAR - https://drive.google.com/file/d/1hAeNqKd-3nXiMhk_t41p4bXXOuE3kcWH/view?usp=sharing Open Source GNU GPL   When testing a program in Android Studio, you must select the debugging mode on a real smartphone

Czech Entropy

  Android APP Beta version of the application. It is necessary to enter the text in English without punctuation marks longer than 100 characters and press the "GENERATE" button. After a while, a set of "random" numbers will be shown as INTEGERS and HEX. They can be copied to the clipboard for use, for example, in XOR encryption. The length of the set of numbers is 60 bytes. The given text is converted into a set of numbers using formulaless technology and is not reversed. So far, the minimally working algorithm has been used. If the sender and receiver select and enter the same text (for example, the same news item published on CNN at 12 o'clock), they will receive the same set of "random" numbers. Attention. The application DOES NOT encrypt data. The application only generates a synchronous set of numbers. It can be seen that while the quality of the set of numbers is not high. Algorithms for choosing "random" numbers can be significa
