💖 CTLOG_STORE_GET0_LOG_BY_ID 💖

okay so bestie, welcome to the 3SSL manual page for CTLOG_STORE_get0_log_by_id — yes the name is a whole mouthful, we do not make the rules, but honestly? once you get it, you'll be obsessed. 🫶

✨ NAME ✨

CTLOG_STORE_get0_log_by_id — get a Certificate Transparency log out of a CTLOG_STORE 🌸

📜 SYNOPSIS 📜

#include <openssl/ct.h>

const CTLOG *CTLOG_STORE_get0_log_by_id(const CTLOG_STORE *store,
                                        const uint8_t *log_id,
                                        size_t log_id_len);

it's giving "three args, one pointer back, no drama." 💅

🦋 DESCRIPTION 🦋

so a Signed Certificate Timestamp (SCT) is out here identifying the Certificate Transparency (CT) log that issued it by using that log's LogID — see RFC 6962, Section 3.2, if you wanna read the source material (respect, honestly).

which means... it's genuinely useful to be able to look up more info about a log (like, say, its public key 👀) using that LogID. main character lookup energy.

CTLOG_STORE_get0_log_by_id() is literally how you do that. it will find a CTLOG inside a CTLOG_STORE that has the LogID you asked for. searching, matching, slaying. 🔥

🎀 RETURN VALUES 🎀

CTLOG_STORE_get0_log_by_id returns a CTLOG with the given LogID if it exists in the given CTLOG_STORE — otherwise it returns NULL. 😭

so like, if you get NULL back it's not a you problem, it's a "that log is not in this store" problem. vibe check accordingly.

👀 SEE ALSO 👀

go read those too, bestie, they're part of the ecosystem. 🌈
