A rainbow table allows inverting a cryptographic function (typically, a hash) at low cost, after a precomputation.

A rainbow table allows inverting a cryptographic function (typically, a hash) at low cost, after a precomputation.

The precomputation evaluates the function at many points (at least, all those for which the function will be invertible), and builds a compact data structure (the rainbow table) allowing later searches at modest cost, with high (or perfect) odds of success.

Are rainbow tables still useful?

With unsalted passwords becoming rare, and stream ciphers having a significantly large state, are there currently any widely deployed systems still vulnerable to such time-memory-data trade-off attacks? If I were to show a small generic improvement…

Multiple Rainbow Tables and their Success Probability

I am trying to understand the calculations for the success probability of finding an unknown key using rainbow tables. Basically, I have a target success probability, a known keyspace of size $N$ and want to derive the neccessary table building…

About the differences between the rainbow table and hellman table

I'm learning the rainbow table and hellman table and I'm curious about the difference between them, so I left a question like this. Wikipedia describes the following sentence: The term, "Rainbow Tables," was first used in Oechslin's initial paper.…

Reduction function Generation

I think I know how rainbow table works , I just wanted to make basic reduction function(for md5) in python with an approach that I am not taking a certain portion of hash but am taking the full hash and introducing below reduction function with an…
