  2. Pseudorandom function family - Wikipedia

    en.wikipedia.org/wiki/Pseudorandom_function_family

    In cryptography, a pseudorandom function family, abbreviated PRF, is a collection of efficiently-computable functions which emulate a random oracle in the following way: no efficient algorithm can distinguish (with significant advantage) between a function chosen randomly from the PRF family and a random oracle (a function whose outputs are fixed completely at random).

  3. Comparison of OTP applications - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_OTP_applications

    The following is a general comparison of OTP applications that are used to generate one-time passwords for two-factor authentication (2FA) systems using the time-based one-time password (TOTP) or the HMAC-based one-time password (HOTP) algorithms.

  4. bcrypt - Wikipedia

    en.wikipedia.org/wiki/Bcrypt

    One brief comment in the text mentions, but does not mandate, the possibility of simply using the ASCII encoded value of a character string: "Finally, the key argument is a secret encryption key, which can be a user-chosen password of up to 56 bytes (including a terminating zero byte when the key is an ASCII string)."

  5. Random password generator - Wikipedia

    en.wikipedia.org/wiki/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.

  6. /dev/random - Wikipedia

    en.wikipedia.org/wiki/Dev/random

    In Unix-like operating systems, /dev/random and /dev/urandom are special files that serve as cryptographically secure pseudorandom number generators (CSPRNGs). They allow access to a CSPRNG that is seeded with entropy (a value that provides randomness) from environmental noise, collected from device drivers and other sources.

  7. Diceware - Wikipedia

    en.wikipedia.org/wiki/Diceware

    Diceware is a method for creating passphrases, passwords, and other cryptographic variables using ordinary dice as a hardware random number generator. For each word in the passphrase, five rolls of a six-sided die are required. The numbers from 1 to 6 that come up in the rolls are assembled as a five-digit number, e.g. 43146. That number is ...

  8. Oblivious pseudorandom function - Wikipedia

    en.wikipedia.org/wiki/Oblivious_Pseudorandom...

    In basic authentication, the server learns the user's password during the course of the authentication. If the server is compromised, this exposes the user's password which compromises the security of the user. With PAKE, however, the user's password is not sent to the server, preventing it from falling into an eavesdropper's hands.

  9. SQL Plus - Wikipedia

    en.wikipedia.org/wiki/SQL_Plus

    An Oracle programmer in the appropriately configured software environment can launch SQL Plus, for example, by entering: $ sqlplus scott/tiger where the Oracle user scott has the password tiger. SQL Plus then presents a prompt with the default form of: SQL>
