Class PBEKey

  +--iaik.security.cipher.PBEKey

All Implemented Interfaces:

Key, SecretKey, Serializable

public class PBEKey

extends Object

implements SecretKey

A secret key for PBE (Password Based Encryption).

Password based encryption as defined in PKCS#5 encrypts the given message with the DES algorithm in CBC mode using a secret key which is derived from a password with the MD2 or MD5 message digest algorithm. PKCS#5 recommends, that the password should consist of printable ASCII characters.

This class uses UTF8 for encoding the password. For password consisting of ASCII characters only this will give the default ASCII encoding.

E.g.: "Beavis" gives the following string of 6 bytes:

0x42 0x65 0x61 0x76 0x69 0x73
