KeyGeneratorSpi
abstract class KeyGeneratorSpi
kotlin.Any | |
↳ | javax.crypto.KeyGeneratorSpi |
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.

Return | |
---|---|
SecretKey! |
the new key |
engineInit
protected abstract fun engineInit(random: SecureRandom!): Unit
Initializes the key generator.
Parameters | |

random |
SecureRandom!: the source of randomness for this generator |
engineInit
protected abstract fun engineInit(
params: AlgorithmParameterSpec!,
random: SecureRandom!
): Unit

params |
AlgorithmParameterSpec!: the key generation parameters |
random |
SecureRandom!: the source of randomness for this key generator |
Exceptions | |

engineInit
protected abstract fun engineInit(
keysize: Int,
random: SecureRandom!
): Unit
Initializes this key generator for a certain keysize, using the given source of randomness.
Parameters | |
---|---|
keysize |
Int: the keysize. This is an algorithm-specific metric, specified in number of bits. |
random |
SecureRandom!: the source of randomness for this key generator |
Exceptions | |
---|---|
java.security.InvalidParameterException |
if the keysize is wrong or not supported. |
