SSL_LIBRARY_INIT(3)

💖 NAME 💖

okay so this is SSL_LIBRARY_INIT(3) from the Library Functions Manual, and it's giving “initialize SSL library by registering algorithms.” The main characters are SSL_library_init, OpenSSL_add_ssl_algorithms, and SSLeay_add_ssl_algorithms. 💅

✨ SYNOPSIS ✨

#include <openssl/ssl.h>

int
SSL_library_init(void);

int
OpenSSL_add_ssl_algorithms(void);

int
SSLeay_add_ssl_algorithms(void);

🦋 DESCRIPTION 🦋

Bestie, first thing first: these functions are deprecated. It is never useful for any application program to call any of them explicitly. The library automatically calls them internally whenever needed, no cap.

• SSL_library_init() registers the available ciphers and digests which are used directly or indirectly by TLS.
• OpenSSL_add_ssl_algorithms() and SSLeay_add_ssl_algorithms() are synonyms for SSL_library_init() and are implemented as macros.

💅 RETURN VALUES 💅

SSL_library_init() always returns 1. iconic.

🎀 SEE ALSO 🎀

🌈 HISTORY 🌈

• SSLeay_add_ssl_algorithms() first appeared in SSLeay 0.8.0 and has been available since OpenBSD 2.4.
• SSL_library_init() first appeared in OpenSSL 0.9.2b and has been available since OpenBSD 2.6.
• OpenSSL_add_ssl_algorithms() first appeared in OpenSSL 0.9.5 and has been available since OpenBSD 2.7.
