KeyPair and KeyPairGenerator Classes

This section describes the KeyPair and KeyPairGenerator Classes. The KeyPairGenerator.generateKeyPair() can be used to generate a private and public key pair. is a final class representing a key pair (a public key and a private key). Major methods in the KeyPair class:

getPrivate() - Returns a PriviateKey object representing the private key in the key pair.

getPublic() - Returns a PublicKey object representing the public key in the key pair. is an abstract class providing a link to implementation classes of private and public key pair generation algorithms provided by various security package providers. Major methods in the KeyPairGenerator class:

getInstance() - Returns a KeyPairGenerator object of the specified algorithm from the implementation of the specified provider. If provider is not specified, the default implementation is used. This is a static method.

initialize() - Initializes the key pair generator with the specified key size.

generateKeyPair() - Generates a key pair and returns a KeyPair object.

getAlgorithm() - Returns the algorithm name of the current key pair generator object.

getProvider() - Returns the provider as a provider object of the current key pair generator object.

See the next section for a sample program on how to use the class.
