Overrides java.security.KeyPairGenerator.initialize.

Initializes the key pair generator with the given parameter set and source of randomness.

public void
initialize(AlgorithmParameterSpec
the parameter set used to generate the keys.
params)

Overrides java.security.KeyPairGenerator.initialize.

Initializes the key pair generator using the specified parameter set and the SecureRandom implementation of the highest-priority installed provider as the source of randomness.

public void
initialize(int
the keysize. This is an algorithm-specific metric, such as modulus length, specified in number of bits.

public KeyPair generateKeyPair()

Overrides java.security.KeyPairGenerator.generateKeyPair.

Doc from 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 genKeyPair.

Returns:KeyPair

the generated key pair

public void initialize(AlgorithmParameterSpec params, SecureRandom random) throws InvalidAlgorithmParameterException

Overrides java.security.KeyPairGenerator.initialize.

Doc from java.security.KeyPairGenerator.initialize.

Initializes the key pair generator with the given parameter set and source of randomness.

This concrete method has been added to this previously-defined abstract class. This method calls the KeyPairGeneratorSpi initialize method, passing it params and random. That initialize method always throws an UnsupportedOperationException if it is not overridden by the provider.

Parameters
params:AlgorithmParameterSpec

the parameter set used to generate the keys.

random:SecureRandom

the source of randomness.

Exceptions
InvalidAlgorithmParameterException:
if the given parameters are inappropriate for this key pair generator.

public void initialize(AlgorithmParameterSpec params) throws InvalidAlgorithmParameterException

Overrides java.security.KeyPairGenerator.initialize.

Doc from java.security.KeyPairGenerator.initialize.

Initializes the key pair generator using the specified parameter set and the SecureRandom implementation of the highest-priority installed provider as the source of randomness. (If none of the installed providers supply an implementation of SecureRandom, a system-provided source of randomness is used.)

This concrete method has been added to this previously-defined abstract class. This method calls the KeyPairGeneratorSpi initialize method, passing it params and a source of randomness (obtained from the highest-priority installed provider or system-provided if none of the installed providers supply one). That initialize method always throws an UnsupportedOperationException if it is not overridden by the provider.

Parameters
params:AlgorithmParameterSpec

the parameter set used to generate the keys.

Exceptions
InvalidAlgorithmParameterException:
if the given parameters are inappropriate for this key pair generator.

public void initialize(int keySize, SecureRandom random)

Overrides java.security.KeyPairGenerator.initialize.

Doc from java.security.KeyPairGenerator.initialize.

Initializes the key pair generator for a certain keysize with the given source of randomness (and a default parameter set).

Parameters
keySize:int

the keysize. This is an algorithm-specific metric, such as modulus length, specified in number of bits.

random:SecureRandom

the source of randomness.
