-RAND_DRBG_new() and RAND_DRBG_secure_new()
-create a new DRBG instance of the given B<type>, allocated from the heap resp.
-the secure heap
-(using OPENSSL_zalloc() resp. OPENSSL_secure_zalloc()).
+RAND_DRBG_new_ex() and RAND_DRBG_secure_new_ex() create a new DRBG instance
+of the given B<type> for the given OPENSSL_CTX <ctx>.
+The <ctx> parameter can be NULL in which case the default OPENSSL_CTX is used.
+RAND_DRBG_new() and RAND_DRBG_secure_new() are the same as RAND_DRBG_new_ex()
+and RAND_DRBG_secure_new_ex() except that the default OPENSSL_CTX is always
+used.
+As of OpenSSL 3.0, there is no different between the new and secure_new
+functions.
 
 RAND_DRBG_set() initializes the B<drbg> with the given B<type> and B<flags>.
+This function is deprecated.  Applications should instead use
+RAND_DRBG_new_ex() to create a new DRBG.
 
 RAND_DRBG_set_defaults() sets the default B<type> and B<flags> for new DRBG
 instances.
