2. Random password generator - Wikipedia

   en.wikipedia.org/wiki/Random_password_generator

   Random password generator. A random password generator is a software program or hardware device that takes input from a random or pseudo-random number generator and automatically generates a password. Random passwords can be generated manually, using simple sources of randomness such as dice or coins, or they can be generated using a computer.

3. Salt (cryptography) - Wikipedia

   en.wikipedia.org/wiki/Salt_(cryptography)

   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 ...

4. One-time password - Wikipedia

   en.wikipedia.org/wiki/One-time_password

   Using a mathematical algorithm to generate a new password based on the previous password (OTPs are effectively a chain and must be used in a predefined order). Using a mathematical algorithm where the new password is based on a challenge (e.g., a random number chosen by the authentication server or transaction details) and/or a counter.

5. bcrypt - Wikipedia

   en.wikipedia.org/wiki/Bcrypt

   Description. The input to the bcrypt function is the password string (up to 72 bytes), a numeric cost, and a 16-byte (128-bit) salt value. The salt is typically a random value. The bcrypt function uses these inputs to compute a 24-byte (192-bit) hash. The final output of the bcrypt function is a string of the form:

6. Password Safe - Wikipedia

   en.wikipedia.org/wiki/Password_Safe

   Password Safe can encrypt any file using a key derived from a passphrase provided by the user through the command-line interface. Password generator. The software features a built-in password generator that generates random passwords. The user may also designate parameters for password generation (length, character set, etc.), creating a "Named ...

7. Time-based one-time password - Wikipedia

   en.wikipedia.org/wiki/Time-based_One-Time_Password

   Time-based one-time password. Time-based one-time password ( TOTP) is a computer algorithm that generates a one-time password (OTP) using the current time as a source of uniqueness. As an extension of the HMAC-based one-time password algorithm (HOTP), it has been adopted as Internet Engineering Task Force (IETF) standard RFC 6238. [1] TOTP is ...

8. Rainbow table - Wikipedia

   en.wikipedia.org/wiki/Rainbow_table

   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 an attacker, they can use a precomputed rainbow table to ...

9. PHP - Wikipedia

   en.wikipedia.org/wiki/PHP

   PHP Version 5 is still used by 15.3% of all websites. It is highly recommended to migrate to PHP 8.1 or later and use random_int() instead of rand() or mt_rand(), as the latter functions are not cryptographically secure. There are two attacks that can be performed over PHP entropy sources: "seed attack" and "state recovery attack".
