+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+On older platforms without a good source of randomness such as \f(CW\*(C`/dev/urandom\*(C'\fR,
+it is possible to query an Entropy Gathering Daemon (EGD) over a local
+socket to obtain randomness and seed the OpenSSL RNG.
+The protocol used is defined by the EGDs available at
+<http://egd.sourceforge.net/> or <http://prngd.sourceforge.net>.
+.PP
+\&\fBRAND_egd_bytes()\fR requests \fBnum\fR bytes of randomness from an EGD at the
+specified socket \fBpath\fR, and passes the data it receives into \fBRAND_add()\fR.
+\&\fBRAND_egd()\fR is equivalent to \fBRAND_egd_bytes()\fR with \fBnum\fR set to 255.
+.PP
+\&\fBRAND_query_egd_bytes()\fR requests \fBnum\fR bytes of randomness from an EGD at
+the specified socket \fBpath\fR, where \fBnum\fR must be less than 256.
+If \fBbuf\fR is \fBNULL\fR, it is equivalent to \fBRAND_egd_bytes()\fR.
+If \fBbuf\fR is not \fBNULL\fR, then the data is copied to the buffer and
+\&\fBRAND_add()\fR is not called.
+.PP
+OpenSSL can be configured at build time to try to use the EGD for seeding
+automatically.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\fBRAND_egd()\fR and \fBRAND_egd_bytes()\fR return the number of bytes read from the
+daemon on success, or \-1 if the connection failed or the daemon did not
+return enough data to fully seed the PRNG.
+.PP
+\&\fBRAND_query_egd_bytes()\fR returns the number of bytes read from the daemon on
+success, or \-1 if the connection failed.
