What is a Rainbow Table?

  1. 1. What is a Rainbow Table ?
  2. 2. A rainbow table is a precomputed table for reversing cryptographic hash functions, usually for cracking password hashes.
  3. 3. Tables are usually used in recovering a plaintext password up to a certain length consisting of a limited set of characters.
  4. 4. It is a practical example of a space/time trade- off, using more computer processing time at the cost of less storage when calculating a hash on every attempt, or less processing time and more storage when compared to a simple lookup table with one entry per hash.
  5. 5. Use of a key derivation function that employs a salt makes this attack infeasible.
  6. 6. Rainbow tables are an application of an earlier, simpler algorithm by Martin Hellman
