javax.crypto
Class KeyGeneratorSpi  

java.lang.Object
  javax.crypto.KeyGeneratorSpi

---

public abstract class KeyGeneratorSpi

extends java.lang.Object

The Service Provider Interface (SPI) for the KeyGenerator class.

Providers wishing to implement a key generator must subclass this and provide an appropriate implementation for all the abstract methods below, and provide an appropriate entry in the master java.security.Provider class (the service name for key generators is "KeyGenerator").

Since:

1.4

---

Constructor Summary

KeyGeneratorSpi()           Create a new key generator SPI.

 

Method Summary
protected abstract  SecretKey	engineGenerateKey()           Generate a key, returning it as a SecretKey.
protected abstract  void	engineInit(java.security.spec.AlgorithmParameterSpec params, java.security.SecureRandom random)           Initialize this key generator with parameters and a source of randomness.
protected abstract  void	engineInit(int keySize, java.security.SecureRandom random)           Initialize this key generator with a key size (in bits) and a source of randomness.
protected abstract  void	engineInit(java.security.SecureRandom random)           Initialize this key generator with a source of randomness; the implementation should use reasonable default parameters (such as generated key size).
