org.apache.sshd.common.util.security.bouncycastle.BouncyCastleRandom

All Implemented Interfaces:

NamedResource, Random

public final class BouncyCastleRandom
extends AbstractRandom

BouncyCastle Random. This pseudo random number generator uses the a very fast PRNG from BouncyCastle. The JRE random will be used when creating a new generator to add some random data to the seed.
