Parameters:

algorithm - the algorithm

Returns:

the new SecureRandomBuilder object

getInstance

public static SecureRandomBuilder getInstance(String algorithm,
                                              String provider)

Gets an instance of SecureRandomBuilder from the given algorithm and provider.

Parameters:

algorithm - the algorithm

provider - the provider

the new SecureRandomBuilder object

algorithm

public SecureRandomBuilder algorithm(@Nonnull
                                     String algorithm)

Sets the algorithm.

Parameters:

algorithm - the algorithm

Returns:

this SecureRandomBuilder object. For chaining.

build

public SecureRandom build()

Returns:

the new SecureRandom object

Throws:

NoSuchAlgorithmException - is thrown if a SecureRandomSpi implementation for the specified algorithm is not available from the specified provider.

NoSuchProviderException - is thrown if the specified provider is not registered in the security provider list.
