/**
|
|
* The implementation of a generic {@link java.security.KeyPairGenerator}
|
|
* adapter class to wrap gnu.crypto keypair generator instances.<p>
|
|
*
|
|
* This class defines the <i>Service Provider Interface</i> (<b>SPI</b>) for the
|
|
* {@link java.security.KeyPairGenerator} class, which is used to generate pairs
|
|
* of public and private keys.<p>
|
|
*
|
|
* All the abstract methods in the {@link java.security.KeyPairGeneratorSpi}
|
|
* class are implemented by this class and all its sub-classes.<p>
|
|
*
|
|
* In case the client does not explicitly initialize the KeyPairGenerator (via
|
|
* a call to an <code>initialize()</code> method), the GNU Crypto provider
|
|
* supplies (and document) default values to be used. For example, the GNU
|
|
* Crypto provider uses a default <i>modulus</i> size (keysize) of 1024 bits for
|
|
* the DSS (Digital Signature Standard) a.k.a <i>DSA</i>.<p>
