Rainbow table. A rainbow table is a precomputed table for caching the outputs of a cryptographic hash function, usually for cracking password hashes. Passwords are typically stored not in plain text form, but as hash values. If such a database of hashed passwords falls into the hands of attackers, they can use a precomputed rainbow table to ...
Password cracking. In cryptanalysis and computer security, password cracking is the process of guessing passwords [ 1] protecting a computer system. A common approach ( brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password. [ 2]
About. If your password is on this list of the 10,000 most common passwords, you need a new password. A hacker can use or generate files like this, which may be readily compiled from breaches of sites such as Ashley Madison. Usually, passwords are not tried one-by-one against a system's secure server online; instead, a hacker might manage to ...
Password complexity rules of enforced symbols were previously used by major platforms such as Google [52] and Facebook, [53] but these have removed the requirement following the discovery that they actually reduced security. This is because the human element is a far greater risk than cracking, and enforced complexity leads most users to highly ...
Everyday, you log into LastPass and it will generate a secure password for any new accounts you make and fill in the password for ones you’ve previously used. Once you install a password manager ...
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 ...

ProPublica explicitly referenced the existence of Facebook's .onion site when they started their own onion service. [5] The site also makes it easier for Facebook to differentiate between accounts that have been caught up in a botnet and those that legitimately access Facebook through Tor. [6]
