Answer 1

It is a good idea to understand the difference between encoding and encryption.

Bluntly put and according to the content that I linked, your "encryption" looks more like encoding (although your intent was to encrypt) especially without the use of encryption keys. That said, should it be your first attempt, it was a very good one. I'm not an expert in cryptography, so take my comments with a grain of salt.
