Method Summary

Modifier and Type	Method and Description
protected SecretKey	Returns: the secret key engineGenerateSecret(KeySpec the specification (key material) of the secret key keySpec) Implements abstract javax.crypto.SecretKeyFactorySpi.engineGenerateSecret. Generates a `SecretKey` object from the provided key specification (key material).
protected KeySpec	Returns: the underlying key specification (key material) in the requested format engineGetKeySpec(SecretKey the key key, Class<?> the requested format in which the key material shall be returned keySpecCl) Implements abstract javax.crypto.SecretKeyFactorySpi.engineGetKeySpec. Returns a specification (key material) of the given key in the requested format.
protected SecretKey	Returns: the translated key engineTranslateKey(SecretKey the key whose provider is unknown or untrusted key) Implements abstract javax.crypto.SecretKeyFactorySpi.engineTranslateKey. Translates a `SecretKey` object, whose provider may be unknown or potentially untrusted, into a corresponding `SecretKey` object of this key factory.

protected SecretKey engineGenerateSecret(KeySpec keySpec) throws InvalidKeySpecException Implements abstract javax.crypto.SecretKeyFactorySpi.engineGenerateSecret. Generates a `SecretKey` object from the provided key specification (key material). Parameters keySpec:KeySpec the specification (key material) of the secret key Returns:SecretKey the secret key Exceptions InvalidKeySpecException: if the given key specification is inappropriate for this key factory to produce a public key.

protected SecretKey engineGenerateSecret(KeySpec keySpec) throws InvalidKeySpecException

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

Parameters

the secret key

Exceptions

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

engineGetKeySpec	back to summary
protected KeySpec engineGetKeySpec(SecretKey key, Class<?> keySpecCl) throws InvalidKeySpecException Implements abstract javax.crypto.SecretKeyFactorySpi.engineGetKeySpec. Returns a specification (key material) of the given key in the requested format. Parameters key:SecretKey the key keySpecCl:Class<?> the requested format in which the key material shall be returned Returns:KeySpec the underlying key specification (key material) in the requested format Exceptions 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).

engineGetKeySpec

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

Parameters

key:SecretKey: the key
keySpecCl:Class<?>: the requested format in which the key material shall be returned

Returns:KeySpec

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

Exceptions

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).
