SSL_GROUP_TO_NAME(3ossl)

💖 SSL_GROUP_TO_NAME 💖

okay bestie, gather round, because this is the SSL_group_to_name page from the OpenSSL 3ossl manual and it's honestly so much simpler than it sounds 🫶

---

✨ NAME ✨

SSL_group_to_name — get the name of a group, fr fr 🎀

---

🌸 SYNOPSIS 🌸

#include <openssl/ssl.h>

const char *SSL_group_to_name(SSL *ssl, int id);

---

🦋 DESCRIPTION 🦋

so like, SSL_group_to_name() is your little lookup bestie 💅 you hand it a TLS group ID and it hands you back the TLS group name that goes with it.

and where do those names come from? built-in or external providers, babes ✨ that's the registration pipeline. same energy as the IDs you'd get handed back from a call to SSL_get1_groups() or SSL_get_shared_group().

so the vibe check is: ID goes in, name comes out. iconic behavior honestly 👑

---

⭐ RETURN VALUES ⭐

• if it's non-NULL, SSL_group_to_name() gives you the TLS group name matching the id you passed, as a NUL-terminated string 🎉
• if it returns NULL, bestie, something went wrong 😭 and possibly no corresponding tlsname got registered during provider initialisation. yeah. that'll do it.

🚨 IMPORTANT ONE, don't skip this: the return value is valid only during the lifetime of the SSL object ssl. so do NOT go holding onto that pointer after ssl is gone, okay? that's giving dangling pointer energy and we do not want 💀
