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!
