Describe how rainbow tables work.
What will be an ideal response?
Rainbow tables make password attacks easier by creating a large pre-generated data set of encrypted passwords. There are two steps to using rainbow tables. First is creating the table itself. Next, that table is used to crack a password. A rainbow table is a compressed representation of plaintext passwords that are related and organized in a sequence (called a chain). To create a rainbow table, each chain begins with an initial password that is encrypted, and then that is fed into a function that produces a different plaintext password. This process is repeated for a set number of rounds. The initial password and the last encrypted value of the chain comprise a rainbow table entry.
