Perhaps it is, but if not you can make it 1 ms or less(which is likely way below other per-request "overhead" that your application incurs anyway)and still benefit from password stretching a lot. Please note that without any stretching a cryptographic primitive could be taking as little as...
known as asalt, to each password before hashing. A salt can be static or generated dynamically. Apassword+saltsequence is fed into the algorithm, which results in a different hash. Thus, pre-computed rainbow tables become useless to hackers. Using this method of ...
The next time the user logs in using their passwords, the server checks whether the password matches the previously created hash. If the two hashes match, the user is then authenticated. The tables used to store password hashes are known as rainbow tables. In most instances, the hacker ...
Rainbow table.When stored in a computer system, passwords are saved as encryptedhash valuesrather than plain text. When you enter your password, it is “hashed”— converted into a predefined-length, undecipherable string that is authenticated against a matching hash value stored in yourpassword ...
