GetInstance(String, Provider)
Returns a SecureRandom object that implements the specified Random Number Generator (RNG) algorithm.

- algorithm
- String
the name of the RNG algorithm. See the SecureRandom section in the Java Cryptography Architecture Standard Algorithm Name Documentation for information about standard RNG algorithm names.
- provider
- Provider
the provider.
Returns
the new SecureRandom object.
- Attributes
Exceptions
if the specified algorithm is not available.
if algorithm is null.
if provider == null
Remarks
Returns a SecureRandom object that implements the specified Random Number Generator (RNG) algorithm.
A new SecureRandom object encapsulating the SecureRandomSpi implementation from the specified Provider object is returned. Note that the specified Provider object does not have to be registered in the provider list.
The returned SecureRandom object has not been seeded. To seed the returned object, call the setSeed method. If setSeed is not called, the first call to nextBytes will force the SecureRandom object to seed itself. This self-seeding will not occur if setSeed was previously called.

Remarks
Returns a SecureRandom object that implements the specified Random Number Generator (RNG) algorithm.
A new SecureRandom object encapsulating the SecureRandomSpi implementation from the specified provider is returned. The specified provider must be registered in the security provider list.
Note that the list of registered providers may be retrieved via the Security#getProviders() Security.getProviders() method.
The returned SecureRandom object has not been seeded. To seed the returned object, call the setSeed method. If setSeed is not called, the first call to nextBytes will force the SecureRandom object to seed itself. This self-seeding will not occur if setSeed was previously called.

Remarks
Returns a SecureRandom object that implements the specified Random Number Generator (RNG) algorithm.
This method traverses the list of registered security Providers, starting with the most preferred Provider. A new SecureRandom object encapsulating the SecureRandomSpi implementation from the first Provider that supports the specified algorithm is returned.
Note that the list of registered providers may be retrieved via the Security#getProviders() Security.getProviders() method.
The returned SecureRandom object has not been seeded. To seed the returned object, call the setSeed method. If setSeed is not called, the first call to nextBytes will force the SecureRandom object to seed itself. This self-seeding will not occur if setSeed was previously called.
