Known direct subclasses KeyPairGenerator KeyPairGenerator The KeyPairGenerator class is used to generate pairs of public and private keys.

---

This class defines the Service Provider Interface (SPI) for the KeyPairGenerator class, which is used to generate pairs of public and private keys.

All the abstract methods in this class must be implemented by each cryptographic service provider who wishes to supply the implementation of a key pair generator for a particular algorithm.

In case the client does not explicitly initialize the KeyPairGenerator (via a call to an initialize method), each provider must supply (and document) a default initialization. For example, the Sun provider uses a default modulus size (keysize) of 1024 bits.

Public methods
abstract KeyPair	generateKeyPair() Generates a key pair.
void	initialize(AlgorithmParameterSpec params, SecureRandom random) Initializes the key pair generator using the specified parameter set and user-provided source of randomness.
abstract void	initialize(int keysize, SecureRandom random) Initializes the key pair generator for a certain keysize, using the default parameter set.
