Rainbow hash tables
WebA good password storage algoithm will have the below properties: Hashing to ensure plain text can not be derrived by reversing the operation. Salting to ensure the hash can not be compared with rainbow tables. Stretching, you need to reiterate the hashing process thousands and thousands of times (depending on the hashing algoithm) to slow down ... WebOct 17, 2024 · Rainbow tables can be quite big as sizes of these can vary from a couple of Gigabytes to Terabytes depending upon different encryption formats, password lengths etc. Formation of Rainbow Table: When a rainbow table is generated then a rainbow hash chain is made. The plaintext is passed through a Hash Function to generate a hash. Then from …
