Let's say we have a number (12345) and we want to store it in the database but encrypted somehow.
We would like to avoid using any common encryption method.
We would like to know if doing this is secure, and if it is, HOW secure.
Original number: 12345
Shuffle: 35124
Add some data: 53412-35124-14352
then you store it on the db...
You can read the original number since you know where to look. Is this method easlily reverse engineered?
