NAME
+ +
+ + genrandom, prng – random number generation
+ +
+

SYNOPSIS
+ +
+ + #include <u.h>
+ #include <libc.h>
+ #include <mp.h>
+ #include <libsec.h> +
+ + void genrandom(uchar *buf, int nbytes) +
+ + void prng(uchar *buf, int nbytes)
+ +
+

DESCRIPTION
+ +
+ + Most security software requires a source of random or, at the + very least, unguessable numbers. +
+ + Genrandom 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 truerand (see rand(3)). +
+ + Prng uses the native rand(3) pseudo-random number generator to + fill the buffer. Used with srand, this function can produce a + reproducible stream of pseudo random numbers useful in testing. + +
+ + Both functions may be passed to mprand (see mp(3)).
