NAME
DSA_generate_key - generate DSA key pair
SYNOPSIS
#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);
DESCRIPTION
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.
RETURN VALUES
DSA_generate_key() returns 1 on success, 0 otherwise.
The error codes can be obtained by ERR_get_error(3).
SEE ALSO
DSA_new(3), ERR_get_error(3), RAND_bytes(3),
DSA_generate_parameters_ex(3)
HISTORY
This function was deprecated in OpenSSL 3.0.
