SCT_PRINT(3ossl)

✨ SCT_print, SCT_LIST_print, SCT_validation_status_string 💖

okay bestie so this is the SCT_PRINT(3ossl) page from the OpenSSL manual, and we're about to make Signed Certificate Timestamps look cute and readable, no cap 🎀

---

🌸 NAME 🌸

SCT_print, SCT_LIST_print, SCT_validation_status_string — these three girlies print Signed Certificate Timestamps in a human-readable way 💅

---

🦋 SYNOPSIS 🦋

#include <openssl/ct.h>

void SCT_print(const SCT *sct, BIO *out, int indent, const CTLOG_STORE *logs);
void SCT_LIST_print(const STACK_OF(SCT) *sct_list, BIO *out, int indent,
                    const char *separator, const CTLOG_STORE *logs);
const char *SCT_validation_status_string(const SCT *sct);

💜 DESCRIPTION 💜

So SCT_print() prints a single Signed Certificate Timestamp — an SCT, iykyk — to a BIO, in a human-readable format. Because raw bytes are giving unreadable 😭

SCT_LIST_print() does basically the same thing but for an entire list of SCTs. And because a list needs boundaries, you can specify a separator to delimit each SCT in the output ✨

The output can also be indented by a specified number of spaces. Cute, right? 🎀

If you pass in a CTLOG_STORE, it gets used to print the description of the CT log that issued each SCT — but only if that log is actually in the CTLOG_STORE. And if you don't want that feature at all? Just pass NULL as the CTLOG_STORE parameter to disable it. Simple as that, periodt 🫶

SCT_validation_status_string() returns the validation status of an SCT as a human-readable string. But — and this is the important part, bestie — you have to call SCT_validate() or SCT_LIST_validate() beforehand in order to set the validation status of an SCT first. No validation, no status, no string. Do it in the right order 🔥

---

👑 RETURN VALUES 👑

SCT_validation_status_string() returns a NUL-terminated string representing the validation status of an SCT object. That's it, that's the return value 🌈

📜 HISTORY 📜

These functions were added in OpenSSL 1.1.0. Old but iconic ⭐

okay that's the whole page, you ate it up fr fr 💖 this was OpenSSL 3.5.9, dated 2026-09-29, and it lives in the SCT_PRINT(3ossl) manual. go forth and print those timestamps, main character 🧚✨
