Method Details

engineGenerateSeed

public byte[] engineGenerateSeed(int numBytes)
Gets a user specified number of bytes specified by the parameter.
Overrides:
engineGenerateSeed in interface SecureRandomSpi
Parameters:
numBytes - number of random bytes to generate
Returns:
an array full of random bytes

engineNextBytes

public void engineNextBytes(byte[] bytes)
Gets a user specified number of bytes depending on the length of the array?
Overrides:
engineNextBytes in interface SecureRandomSpi
Parameters:
bytes - array to fill with random bytes

engineSetSeed

public void engineSetSeed(byte[] seed)
Updates the seed for SecureRandomSpi but does not reset seed. It does to this so repeated called never decrease randomness.
Overrides:
engineSetSeed in interface SecureRandomSpi
