public abstract class KeyPairGeneratorAdapter

extends java.security.KeyPairGenerator

The implementation of a generic java.security.KeyPairGenerator adapter class to wrap gnu.crypto keypair generator instances.

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

All the abstract methods in the java.security.KeyPairGeneratorSpi class are implemented by this class and all its sub-classes.

In case the client does not explicitly initialize the KeyPairGenerator (via a call to an initialize() method), the GNU Crypto provider supplies (and document) default values to be used. For example, the GNU Crypto provider uses a default modulus size (keysize) of 1024 bits for the DSS (Digital Signature Standard) a.k.a DSA.
