摘要

The implications of this increase in computational ability for attackers are severe because attackers can now complete billions of hash operations in a second, making prior forms of password storing methods more vulnerable to brute-force attacks and precomputed attacks. Cipherhash uses a random dynamic multi-algorithm approach by choosing a variations of hashing functions (SHA256, SHA384,..) in different iterations. The output of the previous step becomes the input of the next, the specific sequence of algorithms is saved as a unique sequence string that will be stored together with the final hash. This string is what helps replicate the same hashing process during authentication to validate a match. This approach is applied in a chat app where all the session keys are securely generated with the help of Cipherhash. This method provides an efficient, scalable, and secure way of dealing with sensitive information storage.
