Функции API (API function)

Имя (Name)

gnutls_cipher_decrypt2 - API function


Синопсис (Synopsis)

#include <gnutls/crypto.h>

int gnutls_cipher_decrypt2(gnutls_cipher_hd_t handle, const void * ctext, size_t ctext_len, void * ptext, size_t ptext_len);


Аргументы (Arguments)

gnutls_cipher_hd_t handle is a gnutls_cipher_hd_t type

const void * ctext the data to decrypt

size_t ctext_len the length of data to decrypt

void * ptext the decrypted data

size_t ptext_len the available length for decrypted data


Описание (Description)

This function will decrypt the given data using the algorithm specified by the context. For block ciphers the ctext_len must be a multiple of the block size. For the supported ciphers the plaintext data length will equal the ciphertext size.

Note that in AEAD ciphers, this will not check the tag. You will need to compare the tag sent with the value returned from gnutls_cipher_tag().


Возвращаемое значение (Return value)

Zero or a negative error code on error.
