Class KeyPairGeneratorAdapter

java.lang.Object
  java.security.KeyPairGeneratorSpi
      gnu.crypto.jce.sig.KeyPairGeneratorAdapter

Direct Known Subclasses:

DSSKeyPairGeneratorSpi, RSAKeyPairGeneratorSpi

abstract class KeyPairGeneratorAdapter

extends java.security.KeyPairGeneratorSpi

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

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 the 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.
