Smart Rainbow table is a precomputed lookup table, which can be used to recover the password from its hashed representation. The use of a rainbow table is much faster than a simple brute-force attack (essentially, most hard work for cracking the password has been already done when the rainbow table was created). This method is based on "Rainbow Tables", however we have improved this method a lot, signficiantly reducing the required amount of disk space (to one fourth) and improving the performance.

Smart Rainbow Table Recovery Method can be used in a number of situations. It is particularly good for recovering Windows NT/2000/XP/2003 passwords. It is also applicable for other tasks, such as recovering a password when its hash (MD5, MD4, SHA1 or any other) is known. Smart Table Recovery is based on special precomputed recovery tables. They allow for breaking of long and complex password quite quickly.
