Document DSA and SHA. New function BN_pseudo_rand(). Use BN_prime_checks_size(BN_num_bits(w)) rounds of Miller-Rabin when generating DSA primes (why not use BN_is_prime()?)

DSA_generate_key - generate DSA key pair
Document DSA and SHA. New function BN_pseudo_rand(). Use BN_prime_checks_size(BN_num_bits(w)) rounds of Miller-Rabin when generating DSA primes (why not use BN_is_prime()?)

=head1 SYNOPSIS
#include <openssl/dsa.h>
int DSA_generate_key(DSA *a);
=head1 DESCRIPTION
DSA_generate_key() expects B<a> to contain DSA parameters. It generates
a new key pair and stores it in B<a-E<gt>pub_key> and B<a-E<gt>priv_key>.
man: clarify the 'random number generator must be seeded' requirement The manual pages require for some API functions that the 'random number generator must be seeded' before calling the function. Initially, this was meant literally, i.e. the OpenSSL CSPRNG had to be seeded manually before calling these functions. Since version 1.1.1, the CSPRNG is seeded automatically on first use, so it's not the responsibility of the programmer anymore. Still, he needs to be aware that the seeding might fail.

The random generator must be seeded prior to calling DSA_generate_key().
If the automatic seeding or reseeding of the OpenSSL CSPRNG fails due to
external circumstances (see L<RAND(7)>), the operation will fail.

DSA_generate_key() returns 1 on success, 0 otherwise.
