💖 gnutls_aead_cipher_decryptv2 💖

okay bestie, welcome to the gnutls manual, page for gnutls_aead_cipher_decryptv2 ✨ this one's an API function, and she's lowkey iconic.

🌸 NAME 🌸

gnutls_aead_cipher_decryptv2 — API function

🦋 SYNOPSIS 🦋

#include <gnutls/crypto.h>

int gnutls_aead_cipher_decryptv2(gnutls_aead_cipher_hd_t handle, const
void * nonce, size_t nonce_len, const giovec_t * auth_iov, int
auth_iovcnt, const giovec_t * iov, int iovcnt, void * tag, size_t
tag_size);

✨ ARGUMENTS ✨

bestie there are nine of them, so let's go one by one, no skipping 💅

  • gnutls_aead_cipher_hd_t handle — is a gnutls_aead_cipher_hd_t type. yes, the handle is literally a gnutls_aead_cipher_hd_t. slay, self-explanatory king 👑
  • const void * nonce — the nonce to set 🎀
  • size_t nonce_len — The length of the nonce. (the nonce's little length bestie, they're a package deal)
  • const giovec_t * auth_iov — additional data to be authenticated 🔥
  • int auth_iovcnt — The number of buffers in auth_iov. count 'em up 🌈
  • const giovec_t * iov — the data to decrypt 🔓
  • int iovcnt — The number of buffers in iov. yes another count, we love a counting moment 🧚
  • void * tag — The authentication tag 🏷️
  • size_t tag_size — The size of the tag to use (use zero for the default). zero = default, noted fr fr 📝

💜 DESCRIPTION 💜

This is similar to gnutls_aead_cipher_decrypt(), but it performs in-place encryption on the provided data buffers. like, she's the glow-up version of her predecessor, doing the thing right there in the buffers you handed her 💖

🌟 RETURNS 🌟

Zero or a negative error code on error. that's it, that's the vibe — 0 means we ate, anything negative means we did not eat 😭

🎀 SINCE 🎀

3.6.10 — she's been around, a true vintage icon ✨
