💖 SCT_PRINT(3SSL) — the OpenSSL girlies' guide to printing SCTs 💖

okay so bestie, this page is SCT_PRINT(3SSL) from the OpenSSL fam, and it's all about making Signed Certificate Timestamps actually look like something a human can read. no vibes-based guessing, we're printing them. periodt. ✨

🌸 NAME 🌸

SCT_print, SCT_LIST_print, SCT_validation_status_string — these lil functions print Signed Certificate Timestamps in a human-readable way. yes queen, readable. we love that for us. 💅

🎀 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);

like. look at that. three whole functions. the range. 👑

🦋 DESCRIPTION 🦋

so SCT_print() prints a single Signed Certificate Timestamp (SCT) to a BIO, in a human-readable format. one SCT, one glow-up. ✨

and SCT_LIST_print()? she prints an entire list of SCTs in a similar way. main character energy, obviously. and you can specify a separator to delimit each SCT in the output — so like, you get to choose what goes between them. cute, right? 🎀

now, the output can be indented by a specified number of spaces. (yes, we're being aesthetic about it. it's giving formatted.) and if you hand over 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. iykyk.

alternatively? you can just pass NULL as the CTLOG_STORE parameter to disable that whole feature. lowkey the easiest move if you don't care. 🫶

okay and then SCT_validation_status_string() — she returns the validation status of an SCT as a human-readable string. but listen. you have to call SCT_validate() or SCT_LIST_validate() beforehand in order to set the validation status of an SCT first. do NOT skip that step, bestie, or there's literally nothing to read. 💀

⭐ 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. iconic behavior honestly. 🌟
