CTLOG_STORE_GET0_LOG_BY_ID(3ossl)

💖 NAME 💖

okay so bestie, this is the 3ossl manual page for CTLOG_STORE_get0_log_by_id — and it's literally here to get a Certificate Transparency log from 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);

---

🦋 DESCRIPTION 🦋

A Signed Certificate Timestamp (SCT) identifies the Certificate Transparency (CT) log that issued it using the log's LogID (see RFC 6962, Section 3.2). So yes, it's genuinely useful to be able to look up more information about a log — like, say, its public key — using this LogID ✨

CTLOG_STORE_get0_log_by_id() is the way to do exactly that. It finds a CTLOG in a CTLOG_STORE that has a given LogID, no cap 🫶

---

🎀 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 💀
