Class SecureRandom

java.lang.Object

java.security.SecureRandomSpi

com.ibm.crypto.fips.provider.SecureRandom

All Implemented Interfaces:

AlgorithmStatus, java.io.Serializable

public final class SecureRandom
extends java.security.SecureRandomSpi
implements java.io.Serializable, AlgorithmStatus

This class provides a cryptographically strong pseudo-random number generator based on the SHA1 message digest algorithm. Note that if a seed is not provided, we will generate a seed from a true random number generator(TRNG).
