💖 gnutls_cipher_encrypt — API function 💖

okay bestie, welcome to the gnutls manual, and specifically to gnutls_cipher_encrypt(3). this is the one that actually does the encrypting. the glow-up of your plaintext. the main character moment. let's go 🫶

✨ SYNOPSIS ✨

#include <gnutls/crypto.h>

int gnutls_cipher_encrypt(gnutls_cipher_hd_t handle, void * ptext,
       size_t ptext_len);

like. look at it. three little params and it's out here changing lives 💅

🎀 ARGUMENTS 🎀

  • gnutls_cipher_hd_t handle — bestie this is a gnutls_cipher_hd_t type. it's your cipher handle, your lil context baddie, and it's the one holding the algorithm tea.
  • void * ptext — the data to encrypt. yes, that's your plaintext, and yes, it's getting a whole new look ✨
  • size_t ptext_len — the length of data to encrypt. gotta tell it how many bytes we're working with, no guessing games here 🦋

🌸 DESCRIPTION 🌸

so what does this function actually do, you ask? it encrypts the given data using the algorithm specified by the context. that's it. that's the whole vibe. the context (aka your handle) already knows which algorithm it's on, so this function just takes your data and does the thing. no cap 🔥

⭐ RETURNS ⭐

zero on success, or a negative error code on error. so if you get a negative number back, that's your signal that something went sideways — check it, don't ignore it, periodt 💀

🦋 SINCE 🦋

2.10.0 — she's been iconic since 2.10.0, an absolute veteran 👑
