To be clear, I am speaking truth, but sometimes there is "secure enough". If you strive to only ever use the best security you can find, you would become paralised and would never secure what you needed to secure.

If you apply security beyond your own understanding, there is a good chance you could compromise the security or end up in a situation where you can't figure out how to get access to your protected thing because it is too secure for you.

Don't let perfect be the enemy of good.
