Overview

Rainbow tables are large pre-computed tables that make it fast to determine what word produced a particular hash. Rainbow tables only work if the following conditions are true:

  • The hash algorithm was known when the rainbow table was created;
  • No salt was used in the individual password (because a salt basically gives you a different hash function for every hashed value).
