#include <openssl/dsa.h>
int DSA_generate_key(DSA *a);
DSA_generate_key() expects a to contain DSA parameters. It generates
a new key pair and stores it in a->pub_key and a->priv_key.
The PRNG must be seeded prior to calling DSA_generate_key().
DSA_generate_key() returns 1 on success, 0 otherwise.
The error codes can be obtained by ERR_get_error.
