Although this data structure apparently needs significantly more memory for each secondary structure, the overall increase in space is insignificant, at least in expectation.Second, from the perspective of implementation of hash tables (unordered_map) in C++ STL.It uses chaining.You can specify the ...
This scenario occurs when a pre-4.1 MySQL installation has been upgraded to 4.1 or later but mysql_upgrade has not been run to upgrade the system tables in the mysql database. (This is not a recommended configuration because it does not permit use of more secure 4.1 password hashing.) ...
Notes A bucket is a data type that groups objects together. The term is used in hashing algorithms, where different items that have the same hash code (hash value) go into the same bucket. http://corpus-texmex.irisa.fr References Andoni A E2LSH. http://www.mit.edu/andoni/LSH/ ...

The multi-pass versions are safe as all the blocks have to be kept in memory till the overwrite. 5.3 Attack on iterative compression function Let us consider the following structure of the compression function F (X, Y ), where X and Y are input blocks: • The input blocks of size t...
The difficulties arise when users do not properly create or secure the passwords they choose. For example, it is not uncommon for users to write down passwords and store them in wallets, address books, cell phones, and even sticky notes posted on their monitors. ...
Notes: The upgrade operation just described is safe to execute at any time because it makes the mysql_native_password plugin explicit only for accounts that already use it implicitly. This operation requires no password changes, so it can be performed without affecting users or requiring their ...
