SSL_GET0_GROUP_NAME(3ossl)

💖 SSL_get0_group_name 💖

okay so bestie, welcome to the 3ossl page for SSL_get0_group_name — it's giving "tiny function, huge glow-up" energy. This one lives in the OpenSSL crew, and it's here to spill the tea on which group your TLS session was vibing with during key agreement. ✨

🌸 NAME 🌸

SSL_get0_group_name — get the name of the group that was used for the key agreement of the current TLS session establishment 🫶

---

🎀 SYNOPSIS 🎀

#include <openssl/ssl.h>

const char *SSL_get0_group_name(SSL *s);

---

✨ DESCRIPTION ✨

So like, SSL_get0_group_name() hands you back the name of the group that was used for the key agreement of the current TLS session establishment. That's it. That's the whole thing. Main character behavior honestly. 💅

---

👑 RETURN VALUES 👑

If it's non-NULL, SSL_get0_group_name() returns the name of the group that was used for the key agreement of the current TLS session establishment. Slay.

If SSL_get0_group_name() returns NULL, bestie... an error occurred. 😭 Possibly no TLS session has been established at all. See also SSL_get_negotiated_group(3).

⚠️ Important caveat, no cap: the return value is valid only during the lifetime of the SSL object ssl. Once that object dips, your pointer is giving expired-milk energy. Do not hold onto it. 🙈
