Czech entropy

 Synchronous entropy generators

One, even irreversible transformation of the entered text (in fact, a long password), does not guarantee that some dependence will not be found in the sequence of “random numbers”. The first prototype of the application only demonstrates the technical feasibility.

Using several consecutive non-reversible transformations will greatly reduce the likelihood of calculating the dependence of “random” numbers (increasing the cracking time to a commercially acceptable level). Such a set of numbers can already be effectively used for the second encryption of already encoded text.

The next level of reliability can be achieved by using a software module that generates a variety of non-reversible conversion algorithms while the application is running. Then the only effective way to hack would be to obtain an instance of the application to understand the conversion algorithm used in each specific case.

Those. These are already variants of the application created by the operating party based on the Java project.

Attention. The application DOES NOT ENCRYPTED data. The application only generates a set of pseudo-random numbers.

RSA crypto example Because the RSA algorithm has a higher resistance against decoding, then using it in your personal notepad for a smartphone has advantages. Let's take a ready-made Open Source Java project CryptoNOTE and replace AES encryption with RSA encryption.

  Android Open Java Project 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!   Android Open Java Project ...
