SCT_PRINT(3ossl)

📦 version 3.5.0, in opensuse-leap 16.0

💅 SCT_PRINT(3ossl) — ok bestie, let's print some Signed Certificate Timestamps

Hiii so this is the OpenSSL manual page for SCT_PRINT, and honestly? It's giving "niche but iconic." We're talking about functions that print Signed Certificate Timestamps in a way actual humans can read. ✨

🎀 NAME

SCT_print, SCT_LIST_print, SCT_validation_status_string — these cuties print Signed Certificate Timestamps in a human-readable way. That's the whole vibe. 🫶

✨ SYNOPSIS

Like, here's the include and the signatures, exactly as they are, no cap:

#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

Okay so first up: SCT_print() prints a single Signed Certificate Timestamp (SCT) to a BIO, in a human-readable format. One SCT, one glow-up, one print job. 💖

SCT_LIST_print() does the same thing but for an entire list of SCTs — group-chat energy, everyone gets printed. And you can specify a separator to delimit each SCT in the output, so like, they don't all blur together. 🦋

Both of them let you indent the output by a specified number of spaces. Cute formatting matters, bestie. And if you hand over a CTLOG_STORE, it'll be 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 pass NULL as the CTLOG_STORE parameter to disable this feature entirely. Your call. 💅

Then there's SCT_validation_status_string(), which returns the validation status of an SCT as a human-readable string. The way that works? You gotta call SCT_validate() or SCT_LIST_validate() beforehand in order to set the validation status of an SCT first. No setting, no status — periodt. ⭐

👑 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. 🌈
