The most important part of the invoice is the _payment hash_. When constructing the invoice, Bob will make a payment hash as follows:
1. Bob chooses a random number +r+. This random number is called the _preimage_ or _payment secret_.
2. Bob uses SHA-256 to calculate the hash _H_ of _r_ called the _payment hash_
