💖 SSL_LIBRARY_INIT 💖

okay bestie, this is the OpenSSL page for SSL_library_init, and honestly? it's giving "old faithful but kinda retired". let's get into it 🦋

✨ NAME ✨

SSL_library_init, OpenSSL_add_ssl_algorithms — bestie, these two literally just initialize the SSL library by registering algorithms. that's the whole job. no cap. 💅

🌸 SYNOPSIS 🌸

#include <openssl/ssl.h>

int SSL_library_init(void);

int OpenSSL_add_ssl_algorithms(void);

like yes that's it, two lil functions, one header, we love a simple entrance 👑

🎀 DESCRIPTION 🎀

so SSL_library_init() registers all the available SSL/TLS ciphers and digests. that's literally what it does. iconic behavior, no notes. ✨

and OpenSSL_add_ssl_algorithms()? she's just a synonym for SSL_library_init() — same girl, different name — and she's implemented as a macro. so like, macro energy. 💅

🫶 NOTES 🫶

okay this part MATTERS so listen up:

  • SSL_library_init() must be called before any other action takes place. like, before anything. she's the opener, the main character, the one who goes first. periodt.
  • SSL_library_init() is not reentrant. do not try to be cute and call her from multiple threads at once. she will not have it. 😭

💀 WARNINGS 💀

SSL_library_init() adds ciphers and digests used directly and indirectly by SSL/TLS. like she's out here adding stuff you didn't even ask for because the SSL/TLS stack needs it behind the scenes. quietly doing the most. 🙈

⭐ RETURN VALUES ⭐

SSL_library_init() always returns "1". always. every single time. so bestie, it is 100% safe to just discard the return value — she's never gonna surprise you. 🎀

🌈 SEE ALSO 🌈

go read those too, iykyk 📚✨

👑 HISTORY 👑

the SSL_library_init() and OpenSSL_add_ssl_algorithms() functions were deprecated in OpenSSL 1.1.0 by OPENSSL_init_ssl(). so yeah, they're the vintage pieces now — still cute, but the new girl OPENSSL_init_ssl() took over. it's giving passing the torch. 🕯️

and that's the whole page, babe 🫶 this was OpenSSL version 4.0.3, dated 2026-09-29, serving you SSL_LIBRARY_INIT(3SSL) realness. go call that init before anything else, stay reentrant-safe, and slay 💖✨🎀
