“10. Rainbowcrack – RainbowCrack is a general propose
implementation of Philippe Oechslin”s faster time-memory trade-off
technique. In short, the RainbowCrack tool is a hash cracker. A
traditional brute force cracker try all possible plaintexts one by
one in cracking time. It is time consuming to break complex
password in this way. The idea of time-memory trade-off is to do
all cracking time computation in advance and store the result in
files so called “rainbow table”.”
