Method Summary

Modifier and Type	Method and Description
protected SecretKey	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	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. Translates a key object, whose provider may be unknown or potentially untrusted, into a corresponding key object of this secret-key factory.

engineGenerateSecret	back 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.

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.

engineGetKeySpec	back 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).

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).

engineTranslateKey	back 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.
