Windows Password Recovery - rainbow table attack A rainbow table is a lookup table offering a time-memory tradeoff used in recovering the plaintext password from a password hash generated by a hash function, for example Windows passwords. This is quite a sophisticated password audit tool. This me...

A rainbow table attack uses a pre-generated file containing hashes and their plain text equivalents to crack passwords stored in a database. If there is a match between a hash in the database and one in the rainbow table, the authentication is now possible, the password has been cracked. ...
"Rainbow Table Attack"这个名字来源于一种特殊的数据结构——彩虹表(Rainbow Table),它用于加速破解密码的过程。彩虹表是一种预计算的哈希表,其中存储了明文密码及其对应的哈希值。通过使用彩虹表,攻击者可以在破解密码时避免实时计算哈希值,从而大大加快破解速度。 这个技术的名字之所以叫做"Rainbow Table",是因为在创建...
In this paper, we propose an improved password recovery method based on rainbow table attack which enables the recovery feasibility of long human chosen passwords. We combine advantage of dictionary generator and rainbow table to produce an efficient and smart approach of cracking long and complicated...
How Can a Rainbow Table Attack Be Prevented? Experts believe that the most effective way of combating rainbow table attacks is password salting. The process involves adding “salt” or random data to encrypt a password. That way, each hash becomes unique for each user. Even reused passwords ar...
Techopedia Explains Rainbow Table Attack A password database usually generates a key for a rainbow table and encrypts a password before storing it. When a user enters a password for the nth time, the password is again encrypted with the same key string and then matched with the stored value...
