Hiii bestie 💖 welcome to the 3ossl manual page for SSL_get0_peer_scts — the tiny little accessor that hands you the SCTs that came in. She’s short, she’s useful, and she’s lowkey iconic.

🌸 NAME 🌸

SSL_get0_peer_scts - get SCTs received

✨ SYNOPSIS ✨

#include <openssl/ssl.h>

const STACK_OF(SCT) *SSL_get0_peer_scts(SSL *s);

💅 DESCRIPTION 💅

SSL_get0_peer_scts() returns the signed certificate timestamps (SCTs) that have been received. If this is the first time that this function has been called for a given SSL instance, it will examine the TLS extensions, OCSP response and the peer's certificate for SCTs. Future calls will return the same SCTs.

Like… it does the little detective work once, then remembers the vibe. No cap. 🕵️‍♀️✨

🫶 RESTRICTIONS 🫶

If no Certificate Transparency validation callback has been set (using SSL_CTX_set_ct_validation_callback or SSL_set_ct_validation_callback), this function is not guaranteed to return all of the SCTs that the peer is capable of sending.

Bestie, read that again: not guaranteed to return all of them. It’s giving “probably, but don’t quote me,” so set your callback if you need the full picture. 💀

🎀 RETURN VALUES 🎀

SSL_get0_peer_scts() returns a list of SCTs found, or NULL if an error occurs.
