You’ve been sent on a mission to get some “AES encryption”, and after a quick look you find a multitude of expressions that contain AES. You may have found out that the acronym “AES” stands for Advanced Encryption Standard. You realize that it’s going to take more than a few minutes to find what you need. In fact, AES isn’t nearly enough information on the shopping list. This needs to be done hand-in-hand with more information about what’s available and what trade-off’s you can make, so you can hone in on the best solution for you.
