The default +\&\fB\s-1RAND_METHOD\s0\fR, as set by \fIRAND_set_rand_method()\fR and returned by +\&\fIRAND_get_rand_method()\fR, is only used if no \s-1ENGINE\s0 has been set as the default +\&\*(L"rand\*(R" implementation.

The +mechanisms described below relate solely to the software \s-1PRNG\s0 implementation +built in to OpenSSL and used by default. +.PP These functions implement a cryptographically secure pseudo-random number generator (\s-1PRNG\s0).
