SSL_CONF_CTX_SET_SSL_CTX(3ossl)

📦 version 3.5.0, in opensuse-leap 16.0

💖 SSL_CONF_CTX_SET_SSL_CTX(3ossl) 💖

okay so bestie, this is a page from the OpenSSL manual, section 3ossl, and it's lowkey the glow-up era of config setup: three little functions that decide where your config commands actually land. it's giving "plumbing but make it cute" 🫶

✨ SYNOPSIS ✨

#include <openssl/ssl.h>

void SSL_CONF_CTX_set_ssl_ctx(SSL_CONF_CTX *cctx, SSL_CTX *ctx);
void SSL_CONF_CTX_set_ssl(SSL_CONF_CTX *cctx, SSL *ssl);
int SSL_CONF_CTX_finish(SSL_CONF_CTX *cctx);

like yes, that's the whole vibe. three lines. no cap. 💅

🌸 DESCRIPTION 🌸

SSL_CONF_CTX_set_ssl_ctx()

this one sets the context associated with cctx to the SSL_CTX structure ctx. and listen — any previous SSL or SSL_CTX associated with cctx gets cleared. it's a clean slate moment, iconic behavior honestly. after this, subsequent calls to SSL_CONF_cmd() will be sent to ctx. 🎀

SSL_CONF_CTX_set_ssl()

same energy, different target: it sets the context associated with cctx to the SSL structure ssl. any previous SSL or SSL_CTX associated with cctx? cleared. gone. bye. subsequent calls to SSL_CONF_cmd() will be sent to ssl. ✨

SSL_CONF_CTX_finish()

this one must be called after all configuration operations have been completed. it's the final boss of the setup phase — it's used to finalise any operations or to process defaults. don't skip it, bestie, it's literally in the job description. 🔥

🦋 NOTES 🦋

the context need not be set — or it can be set to NULL, in which case only syntax checking of commands is performed, where possible. so like, vibes-only mode: it checks your spelling but doesn't actually do the thing. 💀

⭐ RETURN VALUES ⭐

SSL_CONF_CTX_set_ssl_ctx() and SSL_CTX_set_ssl() do not return a value. (yes, that's exactly how it's written on the page — copying it verbatim, mwah 💋)

SSL_CONF_CTX_finish() returns 1 for success and 0 for failure. simple. binary. main character energy. 👑
