 =head1 DESCRIPTION
 
-BN_rand() generates a cryptographically strong pseudo-random number of
-B<bits> in length and stores it in B<rnd>.
-If B<bits> is less than zero, or too small to
-accommodate the requirements specified by the B<top> and B<bottom>
+BN_rand_ex() generates a cryptographically strong pseudo-random
+number of I<bits> in length and security strength at least I<strength> bits
+using the random number generator for the library context associated with
+I<ctx>. The function stores the generated data in I<rnd>. The parameter I<ctx>
+may be NULL in which case the default library context is used.
+If I<bits> is less than zero, or too small to
+accommodate the requirements specified by the I<top> and I<bottom>
 parameters, an error is returned.
-The B<top> parameters specifies
+The I<top> parameters specifies
 requirements on the most significant bit of the generated number.
 If it is B<BN_RAND_TOP_ANY>, there is no constraint.
 If it is B<BN_RAND_TOP_ONE>, the top bit must be one.
 If it is B<BN_RAND_TOP_TWO>, the two most significant bits of
 the number will be set to 1, so that the product of two such random
-numbers will always have 2*B<bits> length.
-If B<bottom> is B<BN_RAND_BOTTOM_ODD>, the number will be odd; if it
+numbers will always have 2*I<bits> length.
+If I<bottom> is B<BN_RAND_BOTTOM_ODD>, the number will be odd; if it
 is B<BN_RAND_BOTTOM_ANY> it can be odd or even.
-If B<bits> is 1 then B<top> cannot also be B<BN_RAND_TOP_TWO>.
+If I<bits> is 1 then I<top> cannot also be B<BN_RAND_TOP_TWO>.
+
+BN_rand() is the same as BN_rand_ex() except that the default library context
+is always used.
+
+BN_rand_range_ex() generates a cryptographically strong pseudo-random
+number I<rnd>, of security stength at least I<strength> bits,
+in the range 0 E<lt>= I<rnd> E<lt> I<range> using the random number
+generator for the library context associated with I<ctx>. The parameter I<ctx>
+may be NULL in which case the default library context is used.
 
-BN_rand_range() generates a cryptographically strong pseudo-random
-number B<rnd> in the range 0 E<lt>= B<rnd> E<lt> B<range>.
+BN_rand_range() is the same as BN_rand_range_ex() except that the default
+library context is always used.

 used for generating values that should remain private, and mirror the
 same difference between L<RAND_bytes(3)> and L<RAND_priv_bytes(3)>.
