-/**
- * The basic visible methods of any pseudo-random number generator.
- * <p>
- * The [HAC] defines a PRNG (as implemented in this library) as follows:
- * <ul>
- * <li>"5.6 Definition: A pseudorandom bit generator (PRBG) is said to pass the
- * <em>next-bit test</em> if there is no polynomial-time algorithm which, on
- * input of the first <code>L</code> bits of an output sequence <code>S</code>,
- * can predict the <code>(L+1)</code><sup>st</sup> bit of <code>S</code> with a
- * probability significantly greater than <code>1/2</code>."</li>
- * <li>"5.8 Definition: A PRBG that passes the <em>next-bit test</em>
- * (possibly under some plausible but unproved mathematical assumption such as
- * the intractability of factoring integers) is called a <em>cryptographically
- * secure pseudorandom bit generator</em> (CSPRBG)."</li>
- * </ul>
- * <p>
- * <b>IMPLEMENTATION NOTE</b>: Although all the concrete classes in this
- * package implement the {@link Cloneable} interface, it is important to note
- * here that such an operation, for those algorithms that use an underlying
- * symmetric key block cipher, <b>DOES NOT</b> clone any session key material
- * that may have been used in initialising the source PRNG (the instance to be
- * cloned). Instead a clone of an already initialised PRNG, that uses an
- * underlying symmetric key block cipher, is another instance with a clone of
- * the same cipher that operates with the <b>same block size</b> but without
- * any knowledge of neither key material nor key size.
- * <p>
