getSecureRandomForSeedAlgorithmProvider

public static java.security.SecureRandom getSecureRandomForSeedAlgorithmProvider(java.lang.String algNameSecRandom,
                                                                                 java.security.Provider prov)

Gets the secure random used for the input seed algorithm in the input provider. If the input provider is null, then left the decision to the JDK.

Parameters:

algNameSecRandom - Algorithm name of the seed generator to set.

prov - Provider to use for the seed algorithm.

Returns:

Returns the SecureRandom implementation for the input seed algorithm by the input provider. If not is found, then return null.

getSecureRandomForSeedAlgorithmProviderName

public static java.security.SecureRandom getSecureRandomForSeedAlgorithmProviderName(java.lang.String algNameSecRandom,
                                                                                     java.lang.String provName)

Gets the secure random used for the input seed algorithm in the input provider. If the input provider is null, then left the decision to the JDK.

Parameters:

algNameSecRandom - Algorithm name of the sedd generator to set.

provName - Provider name to use for the seed generator.

Returns:

Returns the SecureRandom implementation for the input seed algorithm by the input provider. If not is found, then return null.

resetAllSecureRandomCache

public static void resetAllSecureRandomCache()

Reset the seed algorithm generator cache.
