Examples of java.security.KeyPairGenerator.generateKeyPair()

java.security.KeyPairGenerator.generateKeyPair()
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 #genKeyPair() genKeyPair}. @return the generated key pair


        KeyPairGenerator keyGen = KeyPairGenerator.getInstance("DH", "BC");


        keyGen.initialize(dhParams);


        KeyPair kp = keyGen.generateKeyPair();


        KeyAgreement keyAgreement = KeyAgreement.getInstance("DH", "BC");


        keyAgreement.init(kp.getPrivate());
        keyAgreement.doPhase(kp.getPublic(), true);
