One list is generated the following way: 1: Someone generates a random input, which is a valid input. 2: Use the hash function on this input. 3: Use the reduction function on this hash to generate a new valid input. 4: … WebA Rainbow Table and Rainbow Table attack. A rainbow table tries to balance this tradeoff between the space and time taken to make the attack more efficient. In this process, we land on to a reduction function that does just the opposite of a hash function. Mapping hashes to plaintext. However, the reduction function does not reverse the hash ...
