Synchronous random number generators PRNG

Let's look at several ways to create software random number generators using external digital streams and without them. Let's write source code for Android Java - prototypes of applications showing the reality of using algorithms.

Generator of "random" numbers using expansion of source information, sampling and correction of source data. (Czech Entropy Application)

We will use TTS technology in this generator - converting the entered text into speech. This option is available in the Android operating system. TTS allows you to significantly increase the volume of data (30-100 thousand times), use different settings to obtain different digital results, ensure repeatability of the results (which makes it possible to build a PRNG), the transformation is “formulaless”. The disadvantages of the algorithm are obvious: the result is easily repeated (if you know the source text), large but not infinite expansion of the data, unstable level of entropy in the obtained data. Because the received data is a sound file, it may contain many repeating and dependent sequences of numbers.
Let's consider possible options for compensating for the shortcomings of such random number generators.
You can come up with (invent) quite a few algorithms for improving the results of such data expanders.
TTS conversion of the entered text several times with different parameters: sound quality, pronunciation speed, male/female voice, timbre, etc. With subsequent mixing of data from several sound files. The complexity of mixing algorithms directly affects the result. For example, you can "reverse" data in one or more audio files before mixing, introduce data shifts, block permutations, etc. At the same time, the repeatability of the results and the possibility of constructing synchronous generators of “random” numbers are preserved.

Android Open Source

  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 ...

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.
