NAMEDSA_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);

---

DESCRIPTIONAll 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)

---

HISTORYThis function was deprecated in OpenSSL 3.0.
