RainbowCrack is a computer program which generates rainbow tables to be used in password cracking. RainbowCrack differs from "conventional" brute force crackers in that it uses large pre-computed tables called rainbow tables to reduce the length of time needed to crack a password drastically. RainbowCrack was developed by Zhu Shuanglei, and implements an improved time-memory trade-off cryptanalysis attack which originated in Philippe Oechslin's Ophcrack.
Some organizations have made RainbowCrack's rainbow tables available free over the internet.
Famous quotes containing the words rainbow and/or crack:
“The true harvest of my daily life is somewhat as intangible and indescribable as the tints of morning or evening. It is a little star-dust caught, a segment of the rainbow which I have clutched.”
—Henry David Thoreau (1817–1862)
““The glacier knocks in the cupboard,
The desert sighs in the bed,
And the crack in the tea-cup opens
A lane to the land of the dead.”
—W.H. (Wystan Hugh)
