Password cracking. In cryptanalysis and computer security, password cracking is the process of recovering passwords [1] from data that has been stored in or transmitted by a computer system in scrambled form. A common approach ( brute-force attack) is to repeatedly try guesses for the password and to check them against an available ...
Wikipedia:Random. On Wikipedia and other sites running on MediaWiki, Special:Random can be used to access a random article in the main namespace; this feature is useful as a tool to generate a random article. Depending on your browser, it's also possible to load a random page using a keyboard shortcut (in Firefox, Edge, and Chrome Alt-Shift + X ).
Random number generation is a process by which, often by means of a random number generator (RNG), a sequence of numbers or symbols that cannot be reasonably predicted better than by random chance is generated. This means that the particular outcome sequence will contain some patterns detectable in hindsight but impossible to foresee.
The paragraph about the problems with the C standard library random number generator is irrelevant. For generation of an ASCII password, as long as the possible range of outputs is larger than the number of acceptable ASCII characters - from decimal 33 to decimal 126 - the absolute size of the output is unimportant.
Passwords are often created to be memorized by users and may contain non-random information such as dictionary words. On the other hand, a key can help strengthen password protection by implementing a cryptographic algorithm which is difficult to guess or replace the password altogether.

This attack is against AES-256 that uses only two related keys and 2 39 time to recover the complete 256-bit key of a 9-round version, or 2 45 time for a 10-round version with a stronger type of related subkey attack, or 2 70 time for an 11-round version. The Advanced Encryption Standard ( AES ), also known by its original name Rijndael ( Dutch ...
In cryptography, a salt is random data fed as an additional input to a one-way function that hashes data, a password or passphrase. [1] Salting helps defend against attacks that use precomputed tables (e.g. rainbow tables ), by vastly growing the size of table needed for a successful attack. [2] [3] [4] It also helps protect passwords that ...
