🌸 NAME 🌸

gnutls_pubkey_verify_data2 — it's an API function, no cap 🫶

---

🎀 SYNOPSIS 🎀

#include <gnutls/abstract.h>

int gnutls_pubkey_verify_data2(gnutls_pubkey_t pubkey,
gnutls_sign_algorithm_t algo, unsigned int flags, const gnutls_datum_t *
data, const gnutls_datum_t * signature);

---

🦋 ARGUMENTS 🦋

• gnutls_pubkey_t pubkey — literally holds the public key, that's her whole job 💅
• gnutls_sign_algorithm_t algo — the signature algorithm that got used, periodt
• unsigned int flags — zero, or an OR list of gnutls_certificate_verify_flags (mix and match as you please)
• const gnutls_datum_t * data — holds the signed data 📦
• const gnutls_datum_t * signature — contains the signature, the whole point of the situation

---

✨ DESCRIPTION ✨

so this function will verify the given signed data, using the parameters from the certificate. that's it, that's the move 🔥

---

👑 RETURNS 👑

if the verification fails, you get GNUTLS_E_PK_SIG_VERIFY_FAILED back. and if it's a success? zero or a positive code, slay 💖

for signatures that are known to be insecure, this function returns GNUTLS_E_INSUFFICIENT_SECURITY — unless you specified the flag GNUTLS_VERIFY_ALLOW_BROKEN. so like… you can, but bestie, be so serious rn 😭

3.0 — she's been iconic since 3.0, iykyk
