DSA_NEW(3SSL)

💖 DSA_new, DSA_free — allocate and free DSA objects 💖

okay bestie, so this is a page from the OpenSSL manual, section 3SSL, and it's called DSA_NEW(3SSL). yes. we're doing DSA today. stay with me, it's short but it's important 🫶

✨ NAME ✨

DSA_new, DSA_free — allocate and free DSA objects

---

🌸 SYNOPSIS 🌸

#include <openssl/dsa.h>

okay so heads up, because this part matters: the following functions have been deprecated since OpenSSL 3.0, and you can hide them entirely by defining OPENSSL_API_COMPAT with a suitable version value — go peek at openssl_user_macros(7) for the deets 👀

DSA* DSA_new(void);

void DSA_free(DSA *dsa);

---

🦋 DESCRIPTION 🦋

All of the functions described on this page are deprecated. like, every single one, bestie 😭 Applications should instead use EVP_PKEY_new(3) and EVP_PKEY_free(3).

DSA_new() allocates and initializes a DSA structure. It is equivalent to calling DSA_new_method(NULL).

DSA_free() frees the DSA structure and its components. The values are erased before the memory is returned to the system. If dsa is NULL, nothing is done. literally nothing, she just vibes 💅

---

⭐ RETURN VALUES ⭐

If the allocation fails, DSA_new() returns NULL and sets an error code that you can obtain with ERR_get_error(3). Otherwise it returns a pointer to the newly allocated structure. slay 🎀

DSA_free() returns no value. she gives nothing and that's her right ✨

👑 SEE ALSO 👑

EVP_PKEY_new(3), EVP_PKEY_free(3), DSA_new(3), ERR_get_error(3), DSA_generate_parameters(3), DSA_generate_key(3)

---

🌈 HISTORY 🌈

All of these functions were deprecated in OpenSSL 3.0. yes, all of them. the whole squad 🙈

aaaand that's the page, bestie 🫶 this was version 4.0.3, dated 2026-09-29, from the DSA_NEW(3SSL) manual. go forth and use EVP_PKEY_new(3) instead, mwah 💋
