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.
