✨ DH_NEW 💖

okay bestie, welcome to the manual page for DH_new(3ossl) — yes that's the OpenSSL one, and yes we're doing this 💅

🌸 NAME 🌸

DH_new, DH_free — the lil duo that allocates and frees DH objects 🦋

🎀 SYNOPSIS 🎀

#include <openssl/dh.h>

okay so first things first, heads up: 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 — peep openssl_user_macros(7) for the deets 👀

DH* DH_new(void);

void DH_free(DH *dh);

💜 DESCRIPTION 💜

  • DH_new() — allocates and initializes a DH structure. that's it, that's the whole vibe ✨
  • DH_free() — frees the DH structure and its components. and no cap, the values get erased before the memory is handed back to the system 🧹 (clean girl behaviour fr fr). oh and if dh is NULL, literally nothing happens — it just doesn't do the thing 🙈

🫶 RETURN VALUES 🫶

if the allocation fails, DH_new() returns NULL and sets an error code that you can grab with ERR_get_error(3). otherwise it hands you back a pointer to the newly allocated structure, slay 💅

DH_free() returns no value. it's giving silent but deadly (in a good way) 💀

🌈 SEE ALSO 🌈

⭐ HISTORY ⭐

all of these functions were deprecated in OpenSSL 3.0 😭

for the replacement, go look at EVP_PKEY-DH(7) — that's your main character now 👑
