SSL_GET_DEFAULT_TIMEOUT(3)

📦 version 4.4.0, in alpine 3.24, arch rolling

💅 SSL_GET_DEFAULT_TIMEOUT 💅

okay bestie, welcome to SSL_get_default_timeout(3) from the Library Functions Manual — yes it's a libssl/libcrypto situation and yes it's about to be the easiest page you read all day 🫶

✨ NAME ✨

SSL_get_default_timeout — get the default session timeout value, that's it, that's the whole vibe 🎀

🌸 SYNOPSIS 🌸

library “libssl” libcrypto

#include <openssl/ssl.h>

long
SSL_get_default_timeout(const SSL *ssl);

🦋 DESCRIPTION 🦋

so SSL_get_default_timeout() hands you back the default timeout value that gets assigned to SSL_SESSION objects negotiated for whatever protocol is valid for ssl. literally just returns it. no side quests 💅

here's the lore: every time a new session gets negotiated, it gets assigned a timeout value, and after that timeout hits it will not be accepted for session reuse anymore. periodt. and if the timeout was never explicitly set with SSL_CTX_set_timeout(3), then the hardcoded default timeout for the protocol is what gets used. iykyk ✨

and SSL_get_default_timeout() is the function that returns that hardcoded value — which is 300 seconds for all currently supported protocols (SSLv2, SSLv3, and TLSv1). five minutes bestie, that's the whole number, no cap 💖

⭐ HISTORY ⭐

SSL_get_default_timeout() first appeared in SSLeay 0.8.0 and has been available since OpenBSD 2.4. iconic behavior from an absolute legend of a function, honestly 🌈👑

ngl there are no flags to memorize here, no environment variables, no exit statuses — just one function returning 300 and living its truth 💀
