NNG_TLS_ENGINE_FIPS_MODE(3tls)

✨ NAME ✨

nng_tls_engine_fips_mode — the girl who tells you if your TLS engine is in FIPS 140-2 mode 💅

So this page lives in the NNG Reference Manual, section 3tls, if you were wondering where to file it in your brain. 🧠✨

🌸 SYNOPSIS 🌸

#include <nng/supplemental/tls/tls.h>

bool nng_tls_engine_fips_mode(void);

---

💖 DESCRIPTION 💖

okay so bestie, nng_tls_engine_fips_mode() is genuinely so simple it's iconic. It returns true if the TLS engine is operating in FIPS 140-2 mode, and false otherwise. That's it. That's the whole function. No arguments, no drama, no surprises. 👑

Tip 💡 FIPS 140-2 references a United States standard for the use of cryptography in information processing systems. So like, it's a whole official government vibe check for crypto. 🇺🇸🔐

Tip 💡 The default TLS engine does not support FIPS 140-2 mode, and will always return false. So if you're out here like "where's my FIPS mode??" — it's not coming, girl. Alternative implementations with such support may be available from commercial suppliers though. 💸✨

Note 📌 Generally the FIPS 140-2 mode cannot be changed after program startup. So whatever mode you woke up in, that's your mode for the rest of the run. No take-backs. periodt. 💀
