Method Detail |

protected abstract void engineSetSeed(byte[] seed)
seed
- the seed.protected abstract void engineNextBytes(byte[] bytes)
If a call to engineSetSeed
had not occurred previously,
the first call to this method forces this SecureRandom implementation
to seed itself. This self-seeding will not occur if
engineSetSeed
was previously called.
bytes
- the array to be filled in with random bytes.protected abstract byte[] engineGenerateSeed(int numBytes)
numBytes
- the number of seed bytes to generate.
