Constructs a secure random number generator (RNG) implementing the
default random number algorithm.
<p> This constructor 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 a SecureRandom (RNG) algorithm is returned.
If none of the Providers support a RNG algorithm,
then an implementation-specific default is returned.
<p> Note that the list of registered providers may be retrieved via
the {@link Security#getProviders() Security.getProviders()} method.
<p> See the SecureRandom section in the <a href=
"{@docRoot}/../technotes/guides/security/StandardNames.html#SecureRandom">
Java Cryptography Architecture Standard Algorithm Name Documentation</a>
for information about standard RNG algorithm names.
<p> The returned SecureRandom object has not been seeded. To seed the
returned object, call the {@code setSeed} method.
If {@code setSeed} is not called, the first call to
{@code nextBytes} will force the SecureRandom object to seed itself.
This self-seeding will not occur if {@code setSeed} was
previously called.
