DSA_generate_key - generate DSA key pair
#include <openssl/dsa.h>
The following functions have been deprecated since OpenSSL 3.0, and can be
hidden entirely by defining
OPENSSL_API_COMPAT with a suitable version
value, see
openssl_user_macros(7):
int DSA_generate_key(DSA *a);
All of the functions described on this page are deprecated. Applications should
instead use
EVP_PKEY_keygen_init(3) and
EVP_PKEY_keygen(3) as
described in
EVP_PKEY-DSA(7).
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 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
RAND(7)), the operation will fail.
DSA_generate_key() returns 1 on success, 0 otherwise. The error codes can
be obtained by
ERR_get_error(3).
DSA_new(3),
ERR_get_error(3),
RAND_bytes(3),
DSA_generate_parameters_ex(3)
This function was deprecated in OpenSSL 3.0.
