Generates a byte array of fixed length filled with random data, often useful for generating salts,
initialization vectors or other seed data. The length is specified as a configuration
value on the underlying implementation.
<p/>
If you'd like per-invocation control the number of bytes generated, use the
{@link #nextBytes(int) nextBytes(int)} method instead.
