Class PBKDF2
java.lang.Object
gnu.crypto.prng.BasePRNG
gnu.crypto.prng.PBKDF2
- All Implemented Interfaces:
- IRandom, Cloneable
public class PBKDF2
- extends BasePRNG
- implements Cloneable
An implementation of the key derivation function KDF2 from PKCS #5:
Password-Based Cryptography (PBE). This KDF is essentially a way to
transform a password and a salt into a stream of random bytes, which may then
be used to initialize a cipher or a MAC.
This version uses a MAC as its pseudo-random function, and the password is
used as the key.
