Ophcrack is a free Windows password cracker based on rainbow tables. It is a very efficient implementation of rainbow tables done by the inventors of the method. It comes with a Graphical User Interface and runs on multiple platforms. It works based on a time-memory trade-off using rainbow tables. This is a new variant of [...]

Ophcrack is a Windows password cracker based on a time-memory trade-off using rainbow tables. This is a new variant of Hellman’s original trade-off, with better performance. It recovers 99.9% of alphanumeric passwords in seconds. We mentioned it in our RainbowCrack and Rainbow Tables article. Changes: (feature) support of the new table set (alphanum + 33 [...]
What is RainbowCrack & Rainbow Tables? RainbowCrack is a general propose implementation of Philippe Oechslin’s faster time-memory trade-off technique. In 1980 Martin Hellman described a cryptanalytic time-memory trade-off which reduces the time of cryptanalysis by using precalculated data stored in memory. This technique was improved by Rivest before 1982 with the introduction of distinguished points [...]
