HMAC-SHA-1 Password-Based Key Derivation Function 2 Boyar-Peralta heuristic
2018/1/29
PBKDF2 [27] is a well-known password-based key derivation function. In order to slow attackers down, PBKDF2 introduces CPU-intensive operations based on an iterated pseudorandom function (in our case ...
Password-based key derivation functions are of particular interest in cryptography because they (a) input a password/passphrase (which usually is short and lacks enough entropy) and derive a cryptogra...
