Problem:
There are examples of mathematics in nature such as Fibonacci number, fractals, etc. Are there examples of encrypted information?
What I am looking for is a pattern that seems random on the surface, but once you put it through a "decryption" process, it is actually something else. Not patterns that seem random because they are complex.
One example that comes close is DNA. But I see DNA as a form of encoding not encryption.
Explain the process of encoding and encryption.
