What is secretkeyfactory in java

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

Methods inherited from class java.lang.Object

Constructor Detail

SecretKeyFactory

protected SecretKeyFactory(SecretKeyFactorySpi keyFacSpi, Provider provider, String algorithm)

Method Detail

getInstance

public static final SecretKeyFactory getInstance(String algorithm) throws NoSuchAlgorithmException

Returns a SecretKeyFactory object that converts secret keys of the specified algorithm. This method traverses the list of registered security Providers, starting with the most preferred Provider. A new SecretKeyFactory object encapsulating the SecretKeyFactorySpi implementation from the first Provider that supports the specified algorithm is returned. Note that the list of registered providers may be retrieved via the Security.getProviders() method.

getInstance

public static final SecretKeyFactory getInstance(String algorithm, String provider) throws NoSuchAlgorithmException, NoSuchProviderException

Returns a SecretKeyFactory object that converts secret keys of the specified algorithm. A new SecretKeyFactory object encapsulating the SecretKeyFactorySpi implementation from the specified provider is returned. The specified provider must be registered in the security provider list. Note that the list of registered providers may be retrieved via the Security.getProviders() method.

getInstance

public static final SecretKeyFactory getInstance(String algorithm, Provider provider) throws NoSuchAlgorithmException

Returns a SecretKeyFactory object that converts secret keys of the specified algorithm. A new SecretKeyFactory object encapsulating the SecretKeyFactorySpi implementation from the specified Provider object is returned. Note that the specified Provider object does not have to be registered in the provider list.

getProvider

getAlgorithm

Returns the algorithm name of this SecretKeyFactory object. This is the same name that was specified in one of the getInstance calls that created this SecretKeyFactory object.

generateSecret

public final SecretKey generateSecret(KeySpec keySpec) throws InvalidKeySpecException

getKeySpec

public final KeySpec getKeySpec(SecretKey key, Class keySpec) throws InvalidKeySpecException

translateKey

public final SecretKey translateKey(SecretKey key) throws InvalidKeyException

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

Class SecretKeyFactory

Key factories are used to convert keys (opaque cryptographic keys of type Key ) into key specifications (transparent representations of the underlying key material), and vice versa. Secret key factories operate only on secret (symmetric) keys.

Key factories are bidirectional, i.e., they allow to build an opaque key object from a given key specification (key material), or to retrieve the underlying key material of a key object in a suitable format.

Application developers should refer to their provider’s documentation to find out which key specifications are supported by the generateSecret and getKeySpec methods. For example, the DESede (Triple DES) secret-key factory supplied by the «SunJCE» provider supports DESedeKeySpec as a transparent representation of Triple DES keys.
