Understanding encryption
- [Instructor] As we start our journey looking at encryption possibilities on the Amazon ecosystem, we're first going to explore concepts around encryption itself 'cause it may be new to you. So to get us started, we're going to look at the key concepts. And those are you start with some sort of data, and that's usually in plaintext or human-readable form, and then with a combination of something called a key and an encryption algorithm, you produce what's called ciphertext, which is unreadable in human form. And in fact, you need to apply reverse encryption or decryption as well as one or more keys in order to make that original data readable again. So the core concepts are data, key, encryption algorithm, and ciphertext. Now this is just a starting point, and encryption has a lot of layers to it. So in this and the next couple of movies, we're going to take a look at these four components and what are some design considerations that you're going to have to consider. So in thinking…
