Method Detail

initialize

public void initialize(int keysize,
                       java.security.SecureRandom random)

Description copied from class: java.security.KeyPairGeneratorSpi

Initialize the KeyPairGeneratorSpi with the specified key size and source of randomness

---

initialize

public void initialize(java.security.spec.AlgorithmParameterSpec params,
                       java.security.SecureRandom random)
                throws java.security.InvalidAlgorithmParameterException

Description copied from class: java.security.KeyPairGeneratorSpi

Initialize the KeyPairGeneratorSpi with the specified AlgorithmParameterSpec and source of randomness This is a concrete method. It may be overridden by the provider and if the AlgorithmParameterSpec class is invalid throw InvalidAlgorithmParameterException. By default this method just throws UnsupportedOperationException.

---

generateKeyPair

public java.security.KeyPair generateKeyPair()

Description copied from class: java.security.KeyPairGeneratorSpi

Generates a KeyPair according the rules for the algorithm. Unless intialized, algorithm defaults will be used. It creates a unique key pair each time.
