What Is Rainbow Table Attack?

Rainbow Table Attack definition and explanation.

A rainbow table is a large database of pre-computed hash values for plain text passwords. The database corresponds to hash values for a large set of passwords. Rainbow table attack is more efficient and effective as compared to brute force. Only simple search and compare operations need to be performed. If the hash matches with the one already stored in the database, the original clear-text password is revealed, which may lead to a compromised account immediately.
