abstract class PBEKeyFactory
extends SecretKeyFactorySpi

This class implements a key factory for PBE keys according to PKCS#5, meaning that the password must consist of printable ASCII characters (values 32 to 126 decimal inclusive) and only the low order 8 bits of each password character are used.

engineGenerateSecret

protected SecretKey engineGenerateSecret(KeySpec keySpec)
                                  throws InvalidKeySpecException

Generates a SecretKey object from the provided key specification (key material).

指定者:

engineGenerateSecret 在类中 SecretKeyFactorySpi

参数:

keySpec - the specification (key material) of the secret key

返回:

the secret key

抛出:

InvalidKeySpecException - if the given key specification is inappropriate for this key factory to produce a public key.

engineGetKeySpec

protected KeySpec engineGetKeySpec(SecretKey key,
                                   Class<?> keySpecCl)
                            throws InvalidKeySpecException

Returns a specification (key material) of the given key in the requested format.

指定者:

engineGetKeySpec 在类中 SecretKeyFactorySpi

参数:

key - the key

keySpec - the requested format in which the key material shall be returned

返回:

the underlying key specification (key material) in the requested format

抛出:

InvalidKeySpecException - if the requested key specification is inappropriate for the given key, or the given key cannot be processed (e.g., the given key has an unrecognized algorithm or format).

engineTranslateKey

protected SecretKey engineTranslateKey(SecretKey key)
                                throws InvalidKeyException

Translates a SecretKey object, whose provider may be unknown or potentially untrusted, into a corresponding SecretKey object of this key factory.

指定者:

engineTranslateKey 在类中 SecretKeyFactorySpi

参数:

key - the key whose provider is unknown or untrusted

返回:

the translated key

抛出:

InvalidKeyException - if the given key cannot be processed by this key factory.
