The API we use to generate the key pairs is in the java.security package. That’s mean we have to import this package into our code. The class for generating the key pairs is KeyPairGenerator. To get an instance of this class we have to call the getInstance() methods by providing two parameters. The first parameter is algorithm and the second parameter is the provider.
After obtaining an instance of the key generator we have to initialize it. The initialize() method takes two parameters, the key size and a source of randomness. We set the key size to 1024 and pass and instance of SecureRandom.
Finally to generate the key pairs we call the generateKeyPair() method of the KeyPairGenerator class. This will return a KeyPair object from where we can get the PrivateKey and PublicKey by calling the getPrivate() and getPublic() method.
