💅 SSL_SESSION_print — the vibe check your TLS session never knew it needed 💅

okay so bestie, this is the SSL_SESSION_PRINT(3SSL) page, and it's literally just about printing info out of a session object. Three little functions, all related, all giving you the receipts on what's inside an SSL_SESSION. Slay.

✨ NAME ✨

SSL_SESSION_print, SSL_SESSION_print_fp, SSL_SESSION_print_keylog — printf information about a session 🫶

🌸 SYNOPSIS 🌸

#include <openssl/ssl.h>

int SSL_SESSION_print(BIO *fp, const SSL_SESSION *ses);
int SSL_SESSION_print_fp(FILE *fp, const SSL_SESSION *ses);
int SSL_SESSION_print_keylog(BIO *bp, const SSL_SESSION *x);

🦋 DESCRIPTION 🦋

So here's the tea, bestie. You've got three ways to dump session info, and which one you pick is fully based on where you want the words to land.

  • SSL_SESSION_print() — prints summary information about the session in ses, and it sends all that over to the BIO called fp. That's it. That's the whole job. 💖
  • SSL_SESSION_print_fp() — same exact energy as SSL_SESSION_print(), but the destination is a FILE called fp instead of a BIO. No cap, that's the only difference.
  • SSL_SESSION_print_keylog() — prints session information to the provided BIO <bp>, but in NSS keylog format. iykyk — that's the format people drop into their environment so Wireshark can decrypt stuff. Anyway, it prints to <bp>, keylog style. 🔥

👑 RETURN VALUES 👑

All three of them — SSL_SESSION_print(), SSL_SESSION_print_fp() and SSL_SESSION_print_keylog — return 1 on success or 0 on error. Periodt. There is no in-between. It's giving binary. 🌈
