+
+<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
+
+ Most security software requires a source of random or, at the
+ very least, unguessable numbers.
+ <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
+
+ <i>Genrandom</i> fills a buffer with bytes from the X9.17 pseudo-random
+ number generator. The X9.17 generator is seeded by 24 truly random
+ bytes read via <i>truerand</i> (see <a href="../man3/rand.html"><i>rand</i>(3)</a>).
+ <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
+
+ <i>Prng</i> uses the native <a href="../man3/rand.html"><i>rand</i>(3)</a> pseudo-random number generator to
+ fill the buffer. Used with <i>srand</i>, this function can produce a
+ reproducible stream of pseudo random numbers useful in testing.
+
+ <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
+
+ Both functions may be passed to <i>mprand</i> (see <a href="../man3/mp.html"><i>mp</i>(3)</a>).<br>
