Class javax.crypto.KeyGeneratorSpi
java.lang.Object
|
+----javax.crypto.KeyGeneratorSpi
- public abstract class KeyGeneratorSpi
- extends Object
This class defines the Service Provider Interface (SPI) for the KeyGenerator
class. All the abstract methods in this class must be implemented by each
cryptographic service provider who wishes to supply the implementation of a
key generator for a particular algorithm.

KeyGeneratorSpi()
- Creates a KeyGeneratorSpi object.
-
engineGenerateKey()
- Generates a secret key.
-
engineInit(AlgorithmParameterSpec, SecureRandom)
- Initialises the key generator with the specified parameter set
and a user-provided source of randomness.
-
engineInit(int, SecureRandom)
- Initialises this key generator for a certain strength, using the
given source of randomness.

KeyGeneratorSpi
public KeyGeneratorSpi()
- Creates a KeyGeneratorSpi object.
engineInit
protected abstract void engineInit(SecureRandom random)
- Initialises the key generator.
- Parameters:
- random - the source of randomness for this generator.
engineInit
protected abstract void engineInit(AlgorithmParameterSpec params,
SecureRandom random) throws InvalidAlgorithmParameterException
- Initialises the key generator with the specified parameter set
and a user-provided source of randomness.
- Parameters:
- params - the key generation parameters
- random - the source of randomness for this key generator
- Throws: InvalidAlgorithmParameterException
- if params is
inappropriate for this key generator.
engineInit
protected abstract void engineInit(int strength,
SecureRandom random)
- Initialises this key generator for a certain strength, using the
given source of randomness.
- Parameters:
- strength - the strength of the key. This is an algorithm-specific
metric specified in number of bits.
- random - the source of randomness for this key generator
engineGenerateKey
protected abstract SecretKey engineGenerateKey()
