Class Overview
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.

|
final
void
|
wait()
Causes the current thread to wait until another thread invokes the
notify() method or the
notifyAll() method for this object. |
|
final
void
|
wait(long timeout, int nanos)
Causes the current thread to wait until another thread invokes the
notify() method or the
notifyAll() method for this object, or
some other thread interrupts the current thread, or a certain
amount of real time has elapsed. |
|
final
void
|
wait(long timeout)
Causes the current thread to wait until either another thread invokes the
