SecretKeyFactorySpi

public abstract class SecretKeyFactorySpi
extends Object

java.lang.Object
↳	javax.crypto.SecretKeyFactorySpi

This class defines the Service Provider Interface (SPI) for the SecretKeyFactory class. All the abstract methods in this class must be implemented by each cryptographic service provider who wishes to supply the implementation of a secret-key factory for a particular algorithm.

A provider should document all the key specifications supported by its secret key factory. For example, the DES secret-key factory supplied by the "SunJCE" provider supports DESKeySpec as a transparent representation of DES keys, and that provider's secret-key factory for Triple DES keys supports DESedeKeySpec as a transparent representation of Triple DES keys.

Protected methods
`abstract SecretKey`	`engineGenerateSecret(KeySpec keySpec)` Generates a `SecretKey` object from the provided key specification (key material).
`abstract KeySpec`	`engineGetKeySpec(SecretKey key, Class keySpec)` Returns a specification (key material) of the given key object in the requested format.
`abstract SecretKey`	`engineTranslateKey(SecretKey key)` Translates a key object, whose provider may be unknown or potentially untrusted, into a corresponding key object of this secret-key factory.

Inherited methods

From class


  
    java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
