The <master> \s-1DRBG\s0 is a global instance, which is not intended to be used directly, but is used internally to reseed the other two instances. .PP These functions here provide access to the shared \s-1DRBG\s0 instances. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBRAND_DRBG_get0_master()\fR returns a pointer to the <master> \s-1DRBG\s0 instance. .PP \&\fBRAND_DRBG_get0_public()\fR returns a pointer to the <public> \s-1DRBG\s0 instance. .PP \&\fBRAND_DRBG_get0_private()\fR returns a pointer to the <private> \s-1DRBG\s0 instance. .SH "NOTES" .IX Header "NOTES" It is not thread-safe to access the <master> \s-1DRBG\s0 instance. The <public> and <private> \s-1DRBG\s0 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 \s-1DRBG\s0 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. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBRAND_DRBG_set_callbacks\fR\|(3), \&\fBRAND_DRBG_set_reseed_defaults\fR\|(3), \&\fBRAND_DRBG_set_reseed_interval\fR\|(3), \&\fBRAND_DRBG_set_reseed_time_interval\fR\|(3), \&\fBRAND_DRBG_set_callbacks\fR\|(3), \&\fBRAND_DRBG_generate\fR\|(3), \&\s-1\fBRAND_DRBG\s0\fR\|(7) .SH "HISTORY" .IX Header "HISTORY" The \s-1RAND_DRBG\s0 functions were added in OpenSSL 1.1.1. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2017\-2019 The OpenSSL Project Authors.
