2. Password cracking - Wikipedia

   en.wikipedia.org/wiki/Password_cracking

   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 ...

3. Key derivation function - Wikipedia

   en.wikipedia.org/wiki/Key_derivation_function

   Example of a Key Derivation Function chain. The output of one KDF function is the input to the next KDF function in the chain. In cryptography, a key derivation function (KDF) is a cryptographic algorithm that derives one or more secret keys from a secret value such as a master key, a password, or a passphrase using a pseudorandom function (which typically uses a cryptographic hash function or ...

4. Passphrase - Wikipedia

   en.wikipedia.org/wiki/Passphrase

   Passphrase. A passphrase is a sequence of words or other text used to control access to a computer system, program or data. It is similar to a password in usage, but a passphrase is generally longer for added security. Passphrases are often used to control both access to, and the operation of, cryptographic programs and systems, especially ...

6. PBKDF2 - Wikipedia

   en.wikipedia.org/wiki/PBKDF2

   The PBKDF2 key derivation function has five input parameters: [9] DK = PBKDF2 (PRF, Password, Salt, c, dkLen) where: PRF is a pseudorandom function of two parameters with output length hLen (e.g., a keyed HMAC) Password is the master password from which a derived key is generated. Salt is a sequence of bits, known as a cryptographic salt.

7. Generator (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Generator_(mathematics)

   Generator (mathematics) The 5th roots of unity in the complex plane under multiplication form a group of order 5. Each non-identity element by itself is a generator for the whole group. In mathematics and physics, the term generator or generating set may refer to any of a number of related concepts. The underlying concept in each case is that ...
