💖 SSL_CTX_SET_CTLOG_LIST_FILE 💖

okay bestie, so this is a page from the OpenSSL manual — section 3SSL — and it's literally all about pulling in a Certificate Transparency log list from a file. no cap. let's get into it 🦋

✨ NAME ✨

SSL_CTX_set_default_ctlog_list_file, SSL_CTX_set_ctlog_list_file — load a Certificate Transparency log list from a file 💅

🌸 SYNOPSIS 🌸

#include <openssl/ssl.h>

int SSL_CTX_set_default_ctlog_list_file(SSL_CTX *ctx);
int SSL_CTX_set_ctlog_list_file(SSL_CTX *ctx, const char *path);

🎀 DESCRIPTION 🎀

okay so here's the tea 🍓

  • SSL_CTX_set_default_ctlog_list_file() loads a list of Certificate Transparency (CT) logs from the default file location, which is "ct_log_list.cnf", found in the directory where OpenSSL is installed. it just… knows where to look. main character energy tbh 👑
  • SSL_CTX_set_ctlog_list_file() loads a list of CT logs from a specific path. you hand it the path, it does the thing. and if you wanna know what the file format is supposed to look like, go check CTLOG_STORE_new(3) — it's all in there 🔥

🫶 NOTES 🫶

ngl this part matters, so pay attention:

  • these functions will NOT clear the existing CT log list — the new stuff gets appended to it. it's giving "add to cart", not "replace cart" 😭
  • so if you actually want to replace the existing list, you gotta hit SSL_CTX_set0_ctlog_store(3) first. periodt 💅
  • and if an error happens while parsing some particular log entry in the file, that log entry just gets skipped. it doesn't nuke the whole thing, it just moves on. iconic resilience honestly 🌈

⭐ RETURN VALUES ⭐

  • SSL_CTX_set_default_ctlog_list_file() and SSL_CTX_set_ctlog_list_file() return 1 if the log list is successfully loaded 💖
  • and they return 0 if an error occurs 😭
heads up bestie: in the case of an error, the log list may have been partially loaded. so like… don't assume it's all-or-nothing, because it very much isn't 🙈
