This is great! I just rewrote all my chapters' first paragraph[^1] using the first advice of this article. I'll give back by sharing an advice I learned from ptatcek: the inverted pyramid.[^2] Here's some example of what I just re-wrote. Chapter 2: - I have talked about cryptographic primitives in the previous chapter, they are constructions that achieve specific security properties and form the building blocks of cryptography. - In the first part of this book you will learn about several important ones. + Attributing global unique identifiers to anything, that's the promise of the first cryptographic construction chapter 3: - In chapter 2, you've learned about an interesting construction --hash functions--that on its own doesn't provide much, but if used in combination with a secure channel allows you to verify the authenticity and integrity of some data. + Mix a hash function with a secret key, and you obtain something called a *message authentication code (MAC)*. chapter 4: - You've learned about authenticated encryption in chapter 4, which is a form of symmetric encryption. - This is an extremely useful cryptographic primitive, yet in the real-world, there exist many situations where different peers do not have a shared secret. + In chapter 4 you learned about authenticated encryption, a cryptographic primitive used to encrypt data but limited by its symmetry: both sides of a connection had to share the same key. + In this chapter, I'll lift this restriction by introducing *asymmetric encryption*: a primitive to encrypt to someone else's key without knowing the key. chapter 12: - For as far as I can remember, the term "crypto" has been used in reference to the field of cryptography. - Recently, I have seen its meaning quickly changing and being used by more and more people to refer to *cryptocurrencies*. + Can cryptography be the basis for a new financial system? + This is what cryptocurrencies have been trying to answer since at least 2008, when Bitcoin was proposed by Satoshi Nakamoto (who to this day has yet to reveal their identity).
