+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+The default RAND API implementation (\fBRAND_OpenSSL()\fR) utilizes three
+shared DRBG instances which are accessed via the RAND API:
+.PP
+The \fIpublic\fR and \fIprivate\fR DRBG are thread-local instances, which are used
+by \fBRAND_bytes()\fR and \fBRAND_priv_bytes()\fR, respectively.
+The \fIprimary\fR DRBG is a global instance, which is not intended to be used
+directly, but is used internally to reseed the other two instances.
+.PP
+The three get functions provide access to the shared DRBG instances.
+.PP
+The two set functions allow the public and private DRBG instances to be
+replaced by another random number generator.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\fBRAND_get0_primary()\fR returns a pointer to the \fIprimary\fR DRBG instance
+for the given OSSL_LIB_CTX \fBctx\fR.
+.PP
+\&\fBRAND_get0_public()\fR returns a pointer to the \fIpublic\fR DRBG instance
+for the given OSSL_LIB_CTX \fBctx\fR.
+.PP
+\&\fBRAND_get0_private()\fR returns a pointer to the \fIprivate\fR DRBG instance
+for the given OSSL_LIB_CTX \fBctx\fR.
+.PP
+\&\fBRAND_set0_public()\fR and \fBRAND_set0_private()\fR return 1 on success and 0
+on error.
+.SH NOTES
+.IX Header "NOTES"
+It is not thread-safe to access the \fIprimary\fR DRBG instance.
+The \fIpublic\fR and \fIprivate\fR DRBG instance can be accessed safely, because
+they are thread-local. Note however, that changes to these two instances
+apply only to the current thread.
+.PP
+For that reason it is recommended not to change the settings of these
+three instances directly.
+Instead, an application should change the default settings for new DRBG instances
+at initialization time, before creating additional threads.
+.PP
+During initialization, it is possible to change the reseed interval
+and reseed time interval.
+It is also possible to exchange the reseeding callbacks entirely.
+.PP
+To set the type of DRBG that will be instantiated, use the
+\&\fBRAND_set_DRBG_type\fR\|(3) call before accessing the random number generation
+infrastructure.
+.PP
+The two set functions, operate on the the current thread.  If you want to
+use the same random number generator across all threads, each thread
+must individually call the set functions.
