Examples of java.security.KeyPairGenerator.genKeyPair()

java.security.KeyPairGenerator.genKeyPair()
Generates a key pair.
If this KeyPairGenerator has not been initialized explicitly, provider-specific defaults will be used for the size and other (algorithm-specific) values of the generated keys.
This will generate a new key pair every time it is called.
This method is functionally equivalent to {@link #generateKeyPair() generateKeyPair}. @return the generated key pair @since 1.2

            throw ne;
        }


        generator.initialize( KEY_SIZE );
        KeyPair keypair = generator.genKeyPair();
        entry.put( KEY_ALGORITHM_AT, keyAlgo );
        
        // Generate the private key attributes 
        PrivateKey privateKey = keypair.getPrivate();
        entry.put( PRIVATE_KEY_AT, privateKey.getEncoded() );
