💖 RSA_NEW(3ossl) 💖

okay bestie, welcome to the RSA_new page from the OpenSSL manuals 🎀 this one's a lil vintage-coded ngl, but we're gonna get through it together, hand in hand 🫶

✨ NAME ✨

RSA_new, RSA_free — allocate and free RSA objects 💅

🌸 SYNOPSIS 🌸

#include <openssl/rsa.h>

so like, fair warning: 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 — check out openssl_user_macros(7) for the deets 👀

RSA *RSA_new(void);

void RSA_free(RSA *rsa);

🦋 DESCRIPTION 🦋

RSA_new() allocates and initializes an RSA structure. It's literally equivalent to calling RSA_new_method(NULL) — same thing, no cap ✨

RSA_free() frees the RSA structure and all its components. and bestie, listen — the key is erased before the memory gets handed back to the system 🧹💀 so your secrets aren't just vibing in freed memory, periodt. If rsa is NULL, nothing happens. literally nothing. it just moves on with its day 🙈

👑 RETURN VALUES 👑

If the allocation fails, RSA_new() returns NULL and sets an error code that you can grab with ERR_get_error(3) 😭 Otherwise it returns a pointer to the newly allocated structure — slay 💅

RSA_free() returns no value. it's a void girlie. gives nothing, takes nothing 🎀

🔥 SEE ALSO 🔥

⭐ HISTORY ⭐

All functions described here were deprecated in OpenSSL 3.0 😔 For a replacement, see EVP_PKEY-RSA(7) — that's the main character now 👑

and that's the whole page bestie, we ate and left no crumbs 🍓 this was version 3.5.9, dated 2026-09-29, brought to you by the RSA_NEW(3ossl) girlies themselves 🌈 mwah, ily, go call EVP_PKEY-RSA(7) instead 💖✨
