Method Detail

setSeed

public void setSeed(byte[] seed)

Overrides:

setSeed in class java.security.SecureRandom

setSeed

public void setSeed(long seed)

Overrides:

setSeed in class java.security.SecureRandom

getAlgorithm

public java.lang.String getAlgorithm()

Overrides:

getAlgorithm in class java.security.SecureRandom

nextBytes

public void nextBytes(byte[] bytes)

Overrides:

nextBytes in class java.security.SecureRandom

nextBytes

public void nextBytes(byte[] bytes,
                      byte[] additionalInput)

Generate a user-specified number of random bytes, passing additional input to the DRBG.

Parameters:

bytes - the array to be filled in with random bytes.

additionalInput - optional additional input for the DRBG, may be null (cast a literal null to byte[], as Java 9 and later also have SecureRandom.nextBytes(byte[], SecureRandomParameters)).

generateSeed

public byte[] generateSeed(int numBytes)

Overrides:

generateSeed in class java.security.SecureRandom

reseed

public void reseed(byte[] additionalInput)

Force a reseed of the DRBG

Parameters:

additionalInput - optional additional input
