SSL_GET1_BUILTIN_SIGALGS(3ossl)

📦 version 3.5.0, in opensuse-leap 16.0

💅 SSL_GET1_BUILTIN_SIGALGS 💅

okay bestie, so this is the 3ossl manual page for SSL_get1_builtin_sigalgs — yes that's a whole mouthful, we're gonna get through it together, i promise 🫶

✨ NAME ✨

SSL_get1_builtin_sigalgs — get the list of built-in signature algorithms. that's it, that's the whole vibe 🌸

🎀 SYNOPSIS 🎀

like, literally just this:

#include <openssl/tls1.h>

char *SSL_get1_builtin_sigalgs(OSSL_LIB_CTX *libctx);

two lines. iconic. no notes. 👑

💖 DESCRIPTION 💖

okay so what this does: it returns the colon-separated list of built-in and available TLS signature algorithms. the whole squad, in one string, separated by : 🦋

and listen — the string it returns? that's yours now. you gotta free it yourself with OPENSSL_free(3). no take-backs, no "the library will handle it", you are the main character responsible for that memory. free it. periodt. 💅

⭐ NOTES ⭐

ngl, the string may be empty (like, strlen==0 empty, not a single character to its name 😭) if none of the built-in TLS signature algorithms can actually be activated. when does that happen? for example when the suitable providers are missing. so like, no providers, no sigalgs, no string content. vibe check failed, but the call still works 💀

🔥 RETURN VALUES 🔥

  • NULL — may be returned if no memory could be allocated. sad, but possible 🙈
  • otherwise — a newly allocated string is always returned 🎉 but bestie, lowkey important: it may have strlen == 0. always allocated, not always full of content. both things are true x

🌈 HISTORY 🌈

this function was added in OpenSSL 3.4. new-ish, but it's been around long enough to be that girl ✨
