Implements abstract javax.crypto.SecretKeyFactorySpi.engineGenerateSecret.

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

protected KeySpec
engineGetKeySpec(SecretKey
the key
key, Class<T>
the requested format in which the key material shall be returned
keySpec)

Implements abstract javax.crypto.SecretKeyFactorySpi.engineGetKeySpec.

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

protected SecretKey
engineTranslateKey(SecretKey
the key whose provider is unknown or untrusted
key)

Implements abstract javax.crypto.SecretKeyFactorySpi.engineTranslateKey.

Method Detail

engineGenerateSecretback to summary
protected SecretKey engineGenerateSecret(KeySpec keySpec) throws InvalidKeySpecException

Implements abstract javax.crypto.SecretKeyFactorySpi.engineGenerateSecret.

Doc from 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 secret-key factory to produce a secret key.
engineGetKeySpecback to summary
protected KeySpec engineGetKeySpec(SecretKey key, Class<T> keySpec) throws InvalidKeySpecException

Implements abstract javax.crypto.SecretKeyFactorySpi.engineGetKeySpec.

Doc from javax.crypto.SecretKeyFactorySpi.engineGetKeySpec.

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

Parameters
key:SecretKey

the key

keySpec:Class<T>

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 (e.g., the algorithms associated with key and keySpec do not match, or key references a key on a cryptographic hardware device whereas keySpec is the specification of a software-based key), or the given key cannot be dealt with (e.g., the given key has an algorithm or format not supported by this secret-key factory).
engineTranslateKeyback to summary
protected SecretKey engineTranslateKey(SecretKey key) throws InvalidKeyException

Implements abstract javax.crypto.SecretKeyFactorySpi.engineTranslateKey.

Doc from javax.crypto.SecretKeyFactorySpi.engineTranslateKey.

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

Parameters
key:SecretKey

the key whose provider is unknown or untrusted

Returns:SecretKey

the translated key

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