Constructor Detail

RandomConfig

public RandomConfig(String algorithm)

The constructor.

Parameters:

algorithm - the hash algorithm.

RandomConfig

public RandomConfig(String algorithm,
                    int reseedCount)

The constructor.

Parameters:

algorithm - the hash algorithm.

reseedCount - the re-seed count.

RandomConfig

public RandomConfig(String algorithm,
                    SecurityProvider provider)

The constructor.

Parameters:

algorithm - the hash algorithm.

provider - the SecurityProvider.

RandomConfig

public RandomConfig(String algorithm,
                    int reseedCount,
                    SecurityProvider provider)

The constructor.

Parameters:

algorithm - the hash algorithm.

reseedCount - the re-seed count.

provider - the SecurityProvider.

Method Detail

getReseedCount

public int getReseedCount()

Returns:

the number of calls to RandomCreator.nextRandom(int) after which the underlying SecureRandom is re-seeded (a smaller random number of random seeds are skipped to reduce predictability even stronger).
