abstract class SecureRandomAdapter

extends java.security.SecureRandomSpi

The implementation of a generic SecureRandom adapter class to wrap gnu.crypto prng instances based on Message Digest algorithms.

This class defines the Service Provider Interface (SPI) for the SecureRandom class, which provides the functionality of a cryptographically strong pseudo-random number generator.

All the abstract methods in the SecureRandomSpi class are implemented by this class and all its sub-classes.
